They tell you it's a geometric sequence, so U2/U1 = r, where U2 is the second term of the sequecne and U1 is the first term of the sequence. Likewise, U3/U2 = r. Set up those two equations, solve for 'a', and they seem to hint you'd find 2 values of 'a' leading to two different 'r' values. 1 Reply Link to post Share on other sites More sharing options...
