Problem: the sum of 55 consecutive integers is 5555 . what is the greatest integer in the set ?
Rationale: "let x be the first integer in the set , then x + 54 is the largest integer . the sum is : x + ( x + 1 ) + ( x + 2 ) + . . . + ( x + 54 ) = 55 x + 54 * 55 / 2 = 55 ( x + 27 ) then x + 27 = 101 x = 74 the largest integer in the set is 74 + 54 = 128 the answer is b ."
annotated_formula: add(add(power(add(add(divide(subtract(subtract(55, const_10), const_2), const_4), const_2), const_2), const_2), power(add(add(add(divide(subtract(subtract(55, const_10), const_2), const_4), const_2), const_2), const_2), const_2)), add(power(divide(subtract(subtract(55, const_10), const_2), const_4), const_2), power(add(divide(subtract(subtract(55, const_10), const_2), const_4), const_2), const_2)))
