Q. Find the sum of the infinite geometric series.6+29+827+3281+…Write your answer as an integer or a fraction in simplest form.__
Identify first term and common ratio: First, we need to identify the first term a and the common ratio r of the geometric series.The first term a is the first number in the series, which is 6.The common ratio r is found by dividing the second term by the first term, which is (29)/6=43.
Check common ratio: Next, we check if the absolute value of the common ratio is less than 1, which is necessary for the sum of an infinite geometric series to exist.Since ∣43∣=0.75, which is less than 1, the series converges and we can find the sum.
Use formula for sum: Now, we use the formula for the sum of an infinite geometric series, which is S=1−ra, where S is the sum, a is the first term, and r is the common ratio.Substitute the values of a and r into the formula: S=1−436.
Calculate the sum: We calculate the sum: S=1−436=416=6×4=24.
