5-86.

Identify the following sequences as arithmetic, geometric, or neither. For the arithmetic and geometric sequences, identify the growth pattern.

1. $12, 144, 1728, …$

1. $0, 5, 10, 15, 20, 25, …$

1. $0, 4, 16, 36, 64, …$

1. $1.5, 2.25, 3.375, 5.0625, …$

Linear sequences progress by repeated addition/subtraction. Exponential sequences progress by repeated multiplication/division.
