Question

2,3,5,7,11,13,17,...

sum=?

Answer 1

Once again, with these kinds of problems we are subtlely asked to find a solution which requires assumptions. We guess at a relationship, a pattern, etc. What if there isn't one? What if we guess something and it works but it is not the intent of the original author.

Example

1. If we assume sequential prime numbers then the next number is 19
2. If we assume this is a repeating series then the next number is 2
3. If we assume a reverse order repeating series like: 2 3 5 7 11 13 17 17 13 11 7 5 3 2 2 3 5 7… then the next number would be 17
4. If we assume a squaring repeating series then 2^2 3^2 5^2…
5. 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.
6. The point: never assume if possible. Get clarification of the intent by the original author.

Hope this'll help you.
