Question

Three geometric sequences are given below.

Answer 1

Answer:

B, A, C

Step-by-step explanation:

Calculating the common ratio for each sequence

A → r = $\frac{40}{160}$ = $\frac{1}{4}$ = 0.25

B → r = $\frac{63}{-21}$ = - 3

C → r = $\frac{12}{8}$ = 1.5

B, A, C ← from least to greatest common ratio
