Question

What is the explicit formula for this geometric sequence?
64,16,4,1,...​

Answer 1

This isn’t a Spanish question this is a math question but good luck on your assignment

Answer 2

a_n=64(1/4)^n-1

Step-by-step explanation:

you use the formula a_n=a_1(r)^n-1.

a_1=64 in this sequence.

r is your ratio which would be 1/4 because you are dividing by 4 each time.
