what is the sum of the multiples of 4 between 19 and 130 inclusive ?
"the fastest way in an ap is to find the average and multiply with total integers . . between 19 and 130 , the smallest multiple of 4 is 20 and largest = 128 . . average = ( 20 + 128 ) / 2 = 148 / 2 = 74 . total numbers = ( 128 - 20 ) / 4 + 1 = 27 + 1 = 28 . . sum = 28 * 74 = 2072 ans d"
multiply(divide(add(subtract(130, const_3), add(19, const_2)), const_2), add(divide(subtract(subtract(130, const_3), add(19, const_2)), 4), const_1))
