In the given question, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice from the options given below:

Given series is $\sqrt{3}, \sqrt{12}, \sqrt{27}, \sqrt{48}, \dots$.

The series form an AP, if the difference between two consecutive terms is the same. 

By simplifying it further, the series can be written as $\sqrt{3}, 2\sqrt{3}, 3\sqrt{3}, 4\sqrt{3}, \mathrm{...}$.

The difference between $a_2-a_1=$$\sqrt{3 }$, 

And the difference between $a_3-a_2=$$\sqrt{3 }$ 

As the common difference is the same, so, the series is an AP series.

Therefore, the assertion statement, “ $\sqrt{3 },\sqrt{ 12 },\sqrt{ 27 },\sqrt{ 48 },\dots$  form an AP” is true and the reason "the common difference between the two consecutive terms is same" is true and supports the given assertion statement.
