19 + 20 + 21 = 60
96+98+100 = 294
The sum of two odd numbers is even and the sum of an even number and an odd number is odd.So the sum of three consecutive odd numbers is odd but 270 is even.Ergo there are no three consecutive odd numbers that sum to 270.Three consecutive numbers that sum to 270 are 89, 90, 91.Three consecutive even numbers that sum to 270 are 88, 90, 92.
The sum of 3 consecutive whole numbers is always equal to 3 times the middle number in that sequence.
The sum of any three consecutive even numbers must be divisible by 3. 32 is not, so there is no solution.
The numbers are -30, -28 and -26.
The sum of two evens is even so the sum of any number of evens is even. It is, therefore, impossible for the sum of three even numbers, whether or not consecutive, to be 57, which is an odd number.
90, 94, 96
19 + 20 + 21 = 60
96+98+100 = 294
2+4+6=12
If n is the first number, n + n + 1 + n + 2 + n + 3 will be the sum, which is 4n + 6. 4n is always even, and 6 is even. Therefore, the sum of four consecutive numbers is always even.
If the average of 3 numbers is 37 then the sum of those numbers = 37 * 3 = 111. Which is an odd number. Adding together even numbers never results in an odd number. Therefore the 3 numbers can not be even numbers; consecutive or otherwise. The question can not be answered.
84 + 86 + 88 = 258
33
Yes, the sum of any three consecutive counting numbers has a factor of 3.
