Answer:
The sum of first 30 terms of the arithmetic progression is <u>2160.</u>
Explanation:
For an arithmetic progression, the sum of first
terms with first term as
and common difference
is given as:

Now, it is given that:

Now, plug in these values and frame two equations in 


Now, we solve equations (1) and (2) for
. Subtract equation (1) from equation (2). This gives,

Now, plug in the value of
in equation (1) and solve for
.

Plug in the values of
in the sum formula to find the sum of first 30 terms.
Now, the sum of first 30 terms is given as:

Therefore, the sum of first 30 terms of the arithmetic progression is 2160.
