Question

7.

Determine whether each sequence is arithmetic or geometric. Sequence 1: 32, 16, 0, –16, ... Sequence 2: 32, 16, 8, 4, ...

A. Both sequences are geometric.
B. Both sequences are arithmetic.
C. Sequence 1 is arithmetic and Sequence 2 is geometric.
D. Sequence 2 is arithmetic and Sequence 1 is geometric.

Answer 1

Answer: C

Step-by-step explanation: Sequence 1 goes down by 16 each time (an equal amount) whereas sequence two halves each time making it a geometric sequence!
