the sum of 77 consecutive integers is 7777 . what is the greatest integer in the set ?
"let x be the first integer in the set . then x + 76 is the largest integer . the sum is : x + ( x + 1 ) + ( x + 2 ) + . . . + ( x + 76 ) = 77 x + 76 * 77 / 2 = 77 ( x + 38 ) then x + 38 = 101 x = 63 the largest integer in the set is 63 + 76 = 139 the answer is a ."
add(add(power(add(add(divide(subtract(subtract(77, const_10), const_2), const_4), const_2), const_2), const_2), power(add(add(add(divide(subtract(subtract(77, const_10), const_2), const_4), const_2), const_2), const_2), const_2)), add(power(divide(subtract(subtract(77, const_10), const_2), const_4), const_2), power(add(divide(subtract(subtract(77, const_10), const_2), const_4), const_2), const_2)))
