There is only one single number that equals 15. That number is 15.
No other number or group of numbers equals 15.
If you'd like to consider 3 consecutive numbers whose sum is 15,
then you might have a look at 4, 5, and 6 .
9
nine, ten and eleven. Three consecutive numbers that total thirty
15+15+1=31
Consecutive means following one another. E and F are consecutive, as are Tuesday and Wednesday and 100 and 101. The number 15 is NOT between any consecutive whole numbers. However, it is between the whole numbers 14 and 16 --- which of course are not consecutive.
Since 270 is an even number, then three consecutive odd numbers cannot add to 270. ,because Odd + odd = even (2 numbers_ Even + odd = odd ( plus a third number) odd + odd = even (plus a fourth number) even + odd = odd (plus a fifth number) Notice from the table that the third odd number gives an odd answer; not an even answer. e.g. three odd numbers 3,5, & 7. 3 + 5 = 8 (even) 8 + 7 = 15 ( odd) et. seq.,
The numbers are 14 and 15.
The numbers are 15, 16 and 17.
The numbers are 11, 13 and 15.
13, 14, 15
They are 14, 15 and 16.
They are: 14+15+16 = 45
nine, ten and eleven. Three consecutive numbers that total thirty
The smallest is 15.
4, 5 and 6
45
17
The numbers are 4, 5 and 6.
48/3 = 16 so the three numbers are 15, 16, 17
