Question

Find the first four terms of the sequence given by the following.
an=6n-7, n=1, 2, 3...

Answer 1

- 1, 5, 11, 17

Explanation:

Substitute n = 1, 2, 3, 4 into the nth term rule

a₁ = 6(1) - 7 = 6 - 7 = - 1

a₂ = 6(2) - 7 = 12 - 7 = 5

a₃ = 6(3) - 7 = 18 - 7 = 11

a₄ = 6(4) - 7 = 24 - 7 = 17
