45, 60, and 75
45, 60, and 75
Multiples of 3 include 3, 6, 9, 12, 15 3 and 6 are consecutive. 6 and 9 are consecutive. 9 and 12 are consecutive and so on.
They are: 14+15+16 = 45
18, 15, 12, 9, 6, 3
You can always guess and check! When they are consecutive, it means they must be the next odd integer up from the last. For this, it is 11, 13, 15. 11+13+15= 39
15, 30, 45
The answer depends on where the "next" starts from!
15.15
The sum of the squares of the three consecutive integers 11, 13, 15 = 515
It is a list of three integers which are all multiples of 15.
Divide the sum of the three consecutive odd integers by 3: 45/3 = 15. The smallest of these integers will be two less than 15 and the largest will be two more than 15, so the three consecutive odd integers will be 13, 15, and 17.
