There are no three consecutive numbers that add up to twenty.Proof:5+6+7=186+7+8=217+8+9 = 24
There are a variety of three digits that add up to 25. Examples include 9, 8 and 8.
Because they're in multiples of three - a quick way to tell if a number is a multiple of three is to add up the digits and see if the digits add up to a multiple of three e.g 576, 5+7+6=18, 1+8=9, 9 is a multiple of three
the three numbers add up 9 + 10 + 8 = 27then divide by that three so27 / 3 = 9making 9 the average.
The factors of 21 that add up to 8 are 1 and 7.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
12, 13, 16 Add three, then add 1, then add three, then add 1, and so on so forth
