I need help ? It’s for math.

Answer 1

Answer:

$a_{15} = 2147483648$

Step-by-step explanation:

first, find the common ratio (r) by dividing the second term by the first term:

r = 32 / 8 = 4

next, write a formula for the geometric sequence:

$a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648$
