### find an expression for the general term of?

find an expression for the general term of these sequences?

C) 144, 121, 100, 81, 64, 49…

F) 2, 3, 7, 16, 32, 57…

I've been trying hard, but i can't seem to find a formula which would work for the nth term.

What did you find when you considered powers of numbers, such as squares?
F) 2, 3, 7, 16, 32, 57…
This one is actually fairly complicated. What did you find when you Googled this sequence?

### Re: find an expression for the general term of?

According to yahoo answer, these are possible general terms

ist series numbering from 1^2..is
Tn=T1+(n+1)(n-1)..or Tn=(13-n)^2..goin down the way..
2nd series is
Tn=T1+[(2n-1)(n-1)n]/6..where T1=first term
