I dont know how this is possible to calculate.My lecture didnt explain it in a way i understand. Can someone please lay out the entire eqaution so i know how to calculate in the future? Thanks! :D

I Forgot the attachment. Opps XD

A geometric sequence can be writen as a, ar, ar^2, ar^3, ar^4, ....

a = 3

ar^3 = 1029

(ar^3)/a = r^3

(1029)/3 = r^3

r^3 = 343

r = 7

Plugging a and r back into our a, ar, ar^2, ar^3, ar^4 equation shows that the series is 3, 21, 147, 1029, ....

I hope that helped. :))

Thank you so much!!!! This totoally helped!!

GOOD solution!
