Question

Write the explicit formula for the geometric sequence.

Answer 1

Answer:

D) $a_{n}$$=64$×$0.5^{n-1}$

Step-by-step explanation:

The answer is D because it is the only answer that has an=64 and a decimal, 64 is your first term and the sequence is getting smaller

AND OR

Answer:

D) $a_{n}$$=64$×$0.5^{n-1}$

Step-by-step explanation:

Explicit Formula: an = a1 · dn-1

a1 = 64, d = 0.5

an = 64 · 0.5n-1
