Question

17. Which sequence follows the rule an = an-1 + 7?

O A.-9, -2,4,9,
B.17, 24, 30, 38,
C. 11, 18, 25, 32
D.-15, -7, 1,8,

Answer 1

C

Explanation:

the rule means that each term = 7 + the term before it

A is wrong because -2 + 7 = 5, not 4

B is wrong because 24 + 7 = 31, not 30

D is wrong because -15 + 7 = -8, not -7
