What do the numbers 2 3 5 7 11 have in common?

What do the numbers 2 3 5 7 11 have in common?

Prime numbers list. List of prime numbers up to 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

What two numbers come next in the following series 1 3 7 13 21?

Originally Answered: What is the next number in the sequence: 1,3,7,13,21,31,43? 57, add 14 to 43. This is a quadratic sequence with second difference 2. In other words, the differences between consecutive terms form another sequence: 2,4,6,8,10,12,… and the differences between terms of this sequence are 2.

Which number will come next in the given number series 1 3 7 15 31?

Hence, “127” is the correct answer.

What is the next sequence of numbers 1 11?

1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, (sequence A005150 in the OEIS). To generate a member of the sequence from the previous member, read off the digits of the previous member, counting the number of digits in groups of the same digit.

What is the next number in the series, 2 3 5 7 11 17?

2 3 5 7 11 13 17 19. The answer is 19. All the numbers in a series are prime numbers, so the prime number next to 17 is 19. 19 is the right answer I think. As it forms a series after 2 adds 1 and then after 3 it adds 2 to make 5 then 11 +2=13

How to figure out the logic of a pattern?

The pattern looks like the first two #s increases by 1 (1 time), next two increases by 2 X the previous increase which was 1 and it happens 2 times, next increase is 2 X previous increase which was 2 and should happen 4 times, so the next number should be 15, then 19, then 23. You have figured a pattern that is perfectly logical!

Is the sequence 2, 3, 5, 11 correct?

Your teacher could not consider that pattern incorrect. However, the sequence 2, 3, 5, 7, 11 are the first five prime numbers. A prime number is a positive integer which has exactly 2 positive integer factore, one factor being 1 and the other factor is the positive number itself.

What’s the next number in the repeating series?

If we assume a squaring repeating series then 2^2 3^2 5^2… If we assume that the numbers have no relationship whatsoever but were selected by chance and chance alone then the next number could be anything. The point: never assume if possible. Get clarification of the intent by the original author. First take a look at series once.
