Multiple and then subtract by 150 that will be your answer
The formula for the volume of a cylinder is V=Bh or V=πr2h
Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]
In short, Option C is your answer!!!!
Let me know, if you have some doubt.
The identity property of addition states that a + 0 = a
Your answer is identity property of addition.
