Use the geometric sequence of numbers 1, 2, 4, 8,…to find the following:
a)What is r, the ratio between 2 consecutive terms?
r = 4/2 = 2
b)Using the formula for the nth term of a geometric sequence, what is the 24th term?
General term of a G. P.
Tn =
a = 1, r = 2 ,n = 24
T 24 =
T 24 =
c)Using the formula for the sum of a geometric series, what is the sum of the first 10 terms?
S n =
Sum of first 10 terms:
S10 =
S 10 =
S 10 = 1023
