Answer to Problem 4RE
The common ratio is
Explanation of Solution
Given information:
Given sequence is,
CALCULATION:
Given sequence is,
To find the common ratio is the amount we multiply by each time in a geometric sequence.
Between the all consecutive terms.
2nd term / 1st term
3rd term / 2nd term
4th term / 3rd term
So, each number is
Hence,
The common ratio is
