what is the 8th term of the geometric sequence with this explicit formula ?

Answer: C.) - 896
Step-by-step explanation:
Given the explicit formula :
An = 7 × (-2)^(n-1)
The 8th term of the geometric sequence using the formula will be :
n = 8
A8 = 7 × (-2)^(8-1)
A8 = 7 × (-2)^7
A8 = 7 × (-128)
A8 = - 896
