Identify a1 and r for the sum of the geometric series. −4, 8, −16, 32,… a1 = r =
a1 = [___]
1/2
Explain why a geometric series with a ratio between zero and one converges and how you find the sum.
A geometric series with a ratio between zero and one converges because its powers r^n approach zero as n becomes large. Using the finite sum formula S_n = a_1(1-r^n)/(1-r), the r^n term approaches zero, leaving the infinite sum S = a_1/(1-r).
