Question

16th term in the geometric sequence 1024, -512, 256, ....

Answer 1

Answer:-1/32

Step-by-step explanation:

First term=a=1024

Common ratio=r=-512/1024

r=-1/2

Using them formula

Tn=a x r^(n-1)

T16=1024 x (-1/2)^(16-1)

T16=1024 x (-1/2)^15

T16=1024 x -1/32768

T16=-1024/32768

T16=-1/32
