Question

What are the first five terms

Answer 1

Its the first choice.

Explanation:

an = the nth term. so:

a1 = 6(1) + 1 = 7

a2 = 6(2) + 1 = 13

a3 = 6(3) + 1 = 19

The common difference is 6.

Answer 2

7, 13, 19, 25, 31

Explanation:

aₙ = 6n + 1

n = 1: a₁ = 6 × 1 + 1 = 6 + 1 = 7

n = 2: a₂ = 6 × 2 + 1 = 12 + 1 = 13

n = 3: a₃ = 6 × 3 + 1 = 18 + 1 = 19

n = 4: a₄ = 6 × 4 + 1 = 24 + 1 = 25

n = 5: a₅ = 6 × 5 + 1 = 30 + 1 = 31
