Question

The general term of a sequence is given by an = 7+3 (n-1) for n > 1.

Which recursive formula defines this sequence?

Answer 1

9514 1404 393

Answer:

E

Explanation:

The general term matches the form ...

an = a1 +d(n -1)

for a1 = 7 and d = 3.

This is the form for the general term of an arithmetic sequence with first term 7 and each successive term 3 more than the previous one.

That description matches the recursive formula ...

a(1) = 7; a(n) = a(n-1) +3 . . . . . choice E
