The general term of a sequence is given by un = 5 ^{3−4n}. Determine whether or not this is a geometric sequence.Find the common ratio if a A geometric sequence has a second term of 30 and a fifth term of −468.75 . Find the common ratio and the first term. common ratio First term In a geometric sequence, u1 = 5 and u5 = 1280. The last term os the sequence is 20480. Given that r is positive, find teh number of terms in the sequence.(Solve the problem and share your working in google classroom.) A geometric sequence has a first term of 81and a fourth term of 3.
