Answer: The answer is 144.
Step-by-step explanation: Let 'a' be the first term and 'd' be the common difference of the given arithmetic progression (A.P.).
According to the given information, A.P. is {0, 4, 8, 12, 16, . . .}, i.e., a=0 and d=4.
The sum of first n terms is given by
So, the sum of first 9 terms is
Thus, the required sum is 144.
