Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 8 terms and select the correct answer below. –195,312 195,312 292,968 –292,968

@Mehek14 what about this

Mehek (mehek14):

hold on this will take a while

OpenStudy (anonymous):

okay

Mehek (mehek14):

B

Mehek (mehek14):

multiply the last term by -5 until you have 8 sums and then add all of them

Mehek (mehek14):

so -3 + 15 + -75 + 375 + -1875 + 9375 + -46875 + 234375 = 195,312
