Detailed Solution

Let the first number be x then two consecutive numbers will be, x+1 and x+2, now we get the equation as,
x+x+1+x+2=366
Or, 3x+3=366
Or, 3x=366−3
Or, x=
3633
Or, x=121
As the first number of the three consecutive number x=121 so the next two numbers are x+1=121+1 = 122 and x+2=121+2 = 123.
The answer we get is
121+122+123=366
The answer is 121, 122 and 123.
