Isaak is writing an explicit formula to represent the sequence.

64, 112, 196, 343, ...

What value should he use as the common ratio in the formula? Write the answer as a decimal rounded to the nearest hundredth.

Respuesta :

In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75

The answer is 1.75 on e2020
