88 = 88
Find 2 consecutive ODD integers whose sum is -88 ANSWER: -45, -43
-88
3 + 88 = 91
Sum_ap = ½ × number_of_terms × (first_term + last_term) For the first 88 multiples of three: number_of_terms = 88 first_term = 1 × 3 = 3 last_term = 88 × 3 = 264 → Sum = ½ × 88 × (3 + 264) = 44 × 267 = 11748
88 + 88 = 176
The sum of the four marks would equal 80 x 4 = 320. Since the sum at present is 65 + 72 + 88 = 225, the remaining result must be 320 - 225 = 95.
1*88, possibly.
