Question

What is the sixth term in the geometric sequence described by this explicit formula? an=-5*(4)^(n-1)

Answer 1

Answer:

-5120

Step-by-step explanation:

Replace the n in the formula by 6.

a6 = -5(4)^(6-1)

= -5 * 4^5

= -5120

Answer 2

Answer:

$a_{6}$ = - 5120

Step-by-step explanation:

To obtain the sixth term substitute n = 6 into the formula

$a_{6}$ = - 5 × $4^{5}$ = - 5 × 1024 = - 5120
