Question

what is the sequence of the following :

2- ...,37,50,...,...,101
3- 1,1,1,3,5,9,....,31,57
4- 1,2,6,15,...,...,92,141
5- 3,5,8,13,...,31,44
6- 3,9,27,...,243,729
7- 1,8,27,...,125,210
8- -2,4,-8,16,...,...,-128

Answer 1

Some of these are simple arithmetic or geometric sequences. Other are easily recognizable powers, such as n^2 or 2^n, or are Fibonacci-like.

Why not take a shot at them and let us know what you come up with?
