Math Problem Statement

  1. Determine whether each sequence is arithmetic or geometricor otherwise. If it is a geometric sequence, find the common ratio.

a) 2, 14, 98, 686,

b) 8. 12, 8, 4, 0,

Solution

Let's analyze each sequence to determine if it's arithmetic, geometric, or neither.

Part (a) Sequence: 2,14,98,686,2, 14, 98, 686, \dots
