Answer:
The numbers are 19,20 and 21
Step-by-step explanation:
Let
x -----> the first consecutive number
x+1 ---> the second consecutive number
x+2 --> the third consecutive number
we know that
x+(x+1)+(x+2)=60
Solve for x
3x+3=60
3x=57
x=19
so
x+1=19+1=20
x+2=19+2=21
therefore
The numbers are 19,20 and 21
