Please assist me in solving this ozi keeps 200 on the first day of September 300 on the second, 400 on the third day of that day.... How much does she save in whole month of September, how many days does it take her to save 15200

[@OninabResources]

a = 200, d = 100 and n = 30 S30 = 30/2(2 × 200 + 29 × 100) = 15(400+29000) = 15×3300 = 49500
