How to get the general term?

What do you mean general term?
I think........
1^1
2^2
3^3
4^4 
Its from arithmetic and geometric sequence chapter.....and what you wrote is not correct.

I agree with "anonymous"
term(n) = n^n
check:
term(1) = 1^1 = 1
term(2) = 2^2 = 4
term(3) =3^3 = 27
term(4) = 4^4 = 256 
odd that it would come from the arithmetic and geometric sequence chapter, unless it is an example of a sequence which is neither.
