The numbers would be 8 + 10 + 12.
The smallest is 55.
That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
5 5 5
Their sum is three times the middle number.
The numbers would be 8 + 10 + 12.
Three consecutive integers have a sum of 12. What is the greatest of these integers?
11
44
That isn't possible. The three consecutive number are assumed to be integers; the sum of three consecutive integers is always a multiple of 3 (try it out).
The smallest is 55.
-13, -15 and -17
That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
5 5 5
Their sum is three times the middle number.
Any two consecutive numbers must comprise one odd and one even number, so their product must be even. Any three consecutive numbers must include two consecutive numbers so the result still applies.
The greatest three digit number that is divisible by 7 is 994.
