Given that Keenan does 8 push ups and increases 2 push ups each day till the total number of push ups reach 30.
Let the total days to 30 push ups be x.
An A.P is formed with first term 8 and common difference 2.
Last term of the A.P = 30
30 = 8 + 2 × (x-1)
=> 11 = x -1
=> x = 12
The number of days taken by Keenan to reach 30 push ups = 12
