Question

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.

0.75
1.75
58
279

Answer 1

Answer:

a(n) = 64*(7/4)^(n - 1)

Step-by-step explanation:
