47, 64, 81, 98, 115
47, 30, 13, 4, 21
-4, -21, 13, 30,47
47,63, 80, 96, 112

Answer 1

first option

Explanation:

Given a₁ = 47 and d = 17

Then to find a term in the sequence add 17 to the previous term, that is

a₁ = 47

a₂ = a₁ + 17 = 47 + 17 = 64

a₃ = a₂ + 17 = 64 + 17 = 81

a₄ = a₃ + 17 = 81 + 17 = 98

a₅ = a₄ + 17 = 98 + 17 = 115

The first 5 terms are 47, 64, 81, 98, 115
