Answer
The first five terms are:
$2, 5, 10, 17, 26$
Work Step by Step
The term is equal to $n^2+1$.
For each term that is in the sequence, we plug in the given value for $n$:
$s_1 = 1^2+1 = 1+1 = 2;
\\s_2= 2^2+1 = 4+1 = 5;
\\s_3= 3^2+1 = 9+1 = 10;
\\s_4= 4^2+1 = 16+1 = 17;
\\s_4= 5^2+1 = 25+1 = 26$
