Show that the volumes of the cylinders in the above diagram form an arithmetic progression and state its common difference.

Hint:
Step 1: List down any three consecutive terms. Example: T 1 , T 2 , T 3 .]
Step 2: Calculate the values of T 3 − T 2  and T 2 − T 1 .
Step 3: If T 3 − T 2 = T 2 − T 1 , then the number sequence is an arithmetic progression]
