Answer:

Step-by-step explanation:
We are going to use the identity
because this identities right hand side matches your expression where
and
.
So we have that
is equal to
.
A(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27
