Question

The first three terms of an arithmetic sequence are as follows. - 7, - 3, 1 Find the next two terms of this sequence

Please help

Answer 1

5, 9

Explanation:

To obtain the next term in a sequence add the common difference d to the previous term.

d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4

Thus

a₄ = a₃ + 4 = 1 + 4 = 5

a₅ = a₄ + 4 = 5 + 4 = 9
