Answer:

B

Step-by-step explanation:

Given the expression

2n + 3

To determine the terms in the sequence generated by this expression

Substitute n = 1, 2, 3, 4, ... into it

a₁ = (2 × 1) + 3 = 2 + 3 = 5

a₂ = (2 × 2) + 3 = 4 + 3 = 7

a₃ = (2 × 3) + 3 = 6 + 3 = 9

a₄ = (2 × 4) + 3 = 8 + 3 = 11

a₅ = (2 × 5) + 3 = 10 + 3 = 13

The first 5 terms of the sequence are 5, 7, 9, 11, 13
