Total 5 rows are given, where number of small circles increased by 2 for first 3 rows and then gradually decreased by 3 in case of last 2 rows. You have to find the actual number to be replaced by the question mark (?) by applying your logic.
In each row, the middle number is only achieved by adding the other numbers put in the small circles in same row except the middle one and then divided the sum by 2.
