If half of the sum is 90 then the full sum must be 180. The three consecutive multiples of 10 which add up to 180 are 50, 60 and 70.
44
20 + 25 + 30 = 75
45, 60, and 75
91
45, 60, and 75
1422, 1431, 1440
No. Odd numbers can be written as the sum of consecutive integers, but some multiples of odd numbers are even.
There is no set of three consecutive integers whose sum is 71.
The sum of three consecutive integers is -72
Let the second of the three consecutive multiples of 6 be 6n Then the first is 6n - 6 and the last is 6n + 6; and: (6n - 6) + 6n + (6n + 6) = 666 → 18n = 666 → n = 37 → the consecutive multiples of 6 which sum to 666 are 216, 222, 228
8A + (8A+8) + (8A+16) = 888 24A + 24 = 888 ===> 24A = 864 ===> A = 36 The multiples are 8A, 8A+8, 8A+16 = 288, 296, 304. Sum = 888.
