15

The answer is 15.

Step-by-step explanation:

f(x) = 5x + 40

f(x)=5(-5)+40

f(x)=-25+40

f(x)=15

whats the

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
