lol np

vocaloid · Answer

for a geometric series, multiply each term by the common ratio to get to the next term

so, if the first term is (-2) and the common ratio is (-1/4), the second term is (-2)*(-1/4) and the third term is (-2)*(-1/4)*(-1/4) and so on...

correct

anonymous · Answer

Yea i guess it was pretty simple >.< xD

0_0youscareme · Answer

for a geometric sequence you can use the equation y=a1*(r)^(n-1) where a1 is the first term and r is the rate and n is nth term that you want
