Then solving for a 1 in both equations and setting them equal to one another, 162 r 4 = − 4374 r 7 You can then solve for r (your common ratio), and subsequently a 1 (your first term). You then have all of the information you need. Share Cite
WebBecause a geometric sequence is an exponential function whose domain is the set of positive integers, and the common ratio is the base of the function, we can write explicit formulas that allow us to find particular terms. an = a1rn−1 a n = a 1 r n − 1.
