Question

What's the missing number?
5, 11, 29, 83, ___

Answer 1

Um, help? :/

Answer 2

They look prime, this is weird to me.

Answer 3

They are prime

Answer 4

That's what I thought..

Answer 5

245
11-5 = 6
29-11 = 18
83-29 = 54
6 18 54 are geometric series so the next is 54 * 3 = 162
missing number is 83 + 162 = 245

Answer 6

I think the pattern is triple the number and subtract 4 to get the next number.
