Question

Find the first five terms in the sequences using the general term:


`a_n = 2n - 5`

Answer 1

- 3, - 1, 1, 3, 5

Explanation:

To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the general term

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₂ = 2(2) - 5 = 4 - 5 = - 1

a₃ = 2(3) - 5 = 6 - 5 = 1

a₄ = 2(4) - 5 = 8 - 5 = 3

a₅ = 2(5) - 5 = 10 - 5 = 5

The first 5 terms are - 3, - 1, 1, 3, 5
