Step-by-step Solution
To find the first five terms of the sequence defined by the formula \( 3n^2 + 10 \), we will substitute \( n = 1, 2, 3, 4, \) and \( 5 \) into the formula.
1. For \( n = 1 \):
\[
3(1^2) + 10 = 3(1) + 10 = 3 + 10 = 13
\]
2. For \( n = 2 \):
\[
3(2^2) + 10 = 3(4) + 10 = 12 + 10 = 22
\]
3. For \( n = 3 \):
\[
3(3^2) + 10 = 3(9) + 10 = 27 + 10 = 37
\]
4. For \( n = 4 \):
\[
3(4^2) + 10 = 3(16) + 10 = 48 + 10 = 58
\]
5. For \( n = 5 \):
\[
3(5^2) + 10 = 3(25) + 10 = 75 + 10 = 85
\]
Thus, the first five terms of the sequence are:
\[
13, 22, 37, 58, 85
\]
Quick Answer
The first five terms are 13, 22, 37, 58, 85.
