Answer:
Step-by-step explanation:
Given:
Consecutive Terms: k-5, k+7, k+55
Required:
Determine the value of k
To do this, we make use of the concept of common ratio.
The common ratio (r) of a geometric sequence is:
In other words:
Where 1, 2 and 3 represents the terms of the progression/sequence
So:
