Question

2, 5, 10, 17, . . .
Which equation represents the rule for finding the nth term of this sequence?

Answer 1

Hint: it includes n^2

Answer 2

lets square the numbers n = 1,2,3...
N = 1 = 1
n= = 2^2 = 4
n = 3 = 3^2 = 9
n=4 4^2 = 16

so we have 1, 4, 9, 16

compare this with the sequence in the question Do you see the pattern?
