the series which satisfies the above condition is

13, 17, 21….97


To find: the sum of all two - digit numbers which when divided by 4, yields 1 as the remainder


So, it is an AP whose first term is 13 and common difference d as 4


Now for the finding number of terms, the formula is



And


n = 22


we know that the sum of AP is given by the formula:



substituting the values in the above equation



s = 1210
