Because 5+6=11
It's all prime numbers. Wish.

Here's what I think: one step at a time.
From a+6, a+8, a+12, a+14 are all prime numbers, you can know a lot of information: one is that a is an odd number, 2 is definitely not good, so these four numbers are all odd numbers;
The second is to subtract the smallest a+6 from the largest a+14, which is equal to 8, so we start from a+6 to a+14, a total of 9 numbers;
The third is that since it is a continuous 9 numbers, remove the even numbers, there can only be 5 odd numbers at most, and the end must be 1,3,5,7,9;
Fourth, a+6 must be greater than 8, so the odd number with 5 at the end must be a composite number, not a prime number, so only the number at the end of 1, 3, 7, and 9 is a prime number, which happens to be 4 numbers;
Fifth, except for the difference at the end, the previous items of these four numbers must be the same. If they are different, they do not meet the conditions given a+6, a+8, a+12, a+14 (they differ by 2, 4, 2), so we can write that these numbers must be b1, b3, b7, b9;
The sixth is to determine b, classified by multiples of 3, b = 3k + 1, 3k + 2, 3k + 3, obviously, from b7, b9, b can only be in the form of 3k + 1;
So a=b1-6=10(3k+1)+1-6=30k+5, because a is a prime number, k=0, so a=5

A cannot be divided by 5 to balance 1, because if a+14 is divisible by 5, it is not a prime number;
A cannot be divided by 5 to balance 2, because if a+8 is divisible by 5, it is not a prime number;
A cannot be divided by 5 and 3, because if a+12 is divisible by 5, it is not a prime number;
A cannot be divided by 5 and remainder by 4, because if a+6 is divisible by 5, it is not a prime number;
So a can only be a multiple of 5. Since a is a prime number, a can only be 5
-
is 5, if a divides by 5, 1 a+14 is divisible by 5.
If a divides by 5, 2 a+8 is divisible by 5.
If a divides by 5, 3 a+12 is divisible by 5.
If a divides by 5, 4 a+6 is divisible by 5.
So a should be a multiple of 5, and since a is a prime number, a must be 5

There is no formula for the prime number, and the source is balanced by the prime number, and the interval between the prime numbers is larger, so the method of bringing in one by one is chosen.
It was found that 7 is the smallest prime number that satisfies the question.
When a=7, hail is done, and the numbers in the question are 11, 13, 17, and 19
-
Because a+4, a+6, a+10, are all perturbed by the prime number of the finch.
Therefore, Xun A must not have a factor of 2, 3, and 5 multiples.
So the minimum number is 7
-
Knowing that the prime numbers a and a+ are both prime numbers, try to find the minimum prime number a that meets the requirements.
1.Let a=2 to verify whether 2+4+16+24+28 is prime; 2.If it is not satisfied, it means that the prime number with the smallest slippage may be greater than 2, then a+1, and then repeat the above steps; 3.
If the requirements are met, then a is the minimum prime number that meets the conditional call. a=5

Agree with the statement on the first floor, I have a similar experience as you, I also liked a classmate in my sophomore year of high school, I like the kind I like very much, but it doesn't seem to be to the point of love, I want to wait until the college entrance examination is over and talk to him, to the first month of college he wrote to me and said that he found the girl he liked, that girl is still my good friend, so I can only bless them, but, I always feel that things that are not always so beautiful, in the past few years, I have never forgotten him, but I stubbornly did not go far to contact him, Until I saw him again at this year's New Year's party, he had already broken up with my good friend and was single, but in the chat, I found that he has grown up now, and he is a big boy I don't know at all. So I think it's normal for you to feel this way. It's a commonality
Lazy to eat, smoke, drink, gamble, short-tempered, boastful, unhygienic, unmotivated, unassertive, talking about people behind his back, accomplishing nothing, self-righteous, feeling that the whole world is right and others are wrong, having two stinky money that he thinks is great, and all the money he earns is used on himself. Men can have no car or house, but they are not at least self-motivated. After complaining, I don't love you at all.
The illegal and criminal thing of opening a foot massage shop is to make money, so is the money earned spent at home? If it is spent at home, be considerate of your father's intentions, patiently persuade him, and let him understand that there is a price to be paid for some money, and this price is unbearable for your family. If you are studying, you must study hard, and strive to have the ability to help your family share the burden in the future. >>>More
