If we do 1 push up repetition per day, 3 sets, then increase it by one rep per week for same three sets, how many push ups will we be doing in 6months?
in case one push up repetition means two push ups, 3 sets will count 6 push ups
increasing one rep every week means A.P with first term of 6, common difference of 6 as well and 26 terms making 6 months
the answer should be sum=(26/2)*(2*6+25*6) that is 2106
