Answer 1

Find the 10th term of the following sequence:

-5, -10, -20 . . .
2 • (-5)9 2 • (-5)10
-5 • 29 -5 • 210

Answer 2

the n'th term of a geometric sequence is a*r^(n-1), where a is the first term and r is the common ratio

so 10th term is -5*2^(9) = -5*64*8 = -320*8 = -2560

Answer 3

SO wait which one is it out of the list

Answer 4

it's none of them...it's -5*512
