Question

Calculate the missing terms of the geometric sequence ...,2,?,?,?,512,... Select all that apply.A 129.5, 257, 384.5B. 12, 72, 2880 C. 8.32, 128D. -129.5,257,-384.5E -12,72,-288F-8,32,-128

Answer 1

The first term is 2. Every term is four times the previous one. So, the second term is 8, the third term is 32 and the fourth term is 128.

There is one more possibility. Every term is negative four times the previous one. So, the second term is -8, the third term is 32, and the fourth term is -128.

Thus, the correct options are C and F.
