Question

Sum of three consecutive numbers is 63. Find all these numbers

Answer 1

Answer:

x+(x+1)+(x+2)=63

x+x+1+x+2=63

3x+3=63

3x=63-3

3x=60

x=60/3

x=20

first no=x=20

2nd no=x+1=20+1=21

3rd no=x+2=20+2=22

1st+2nd+3rd=63

20+21+22=63

63=63

Answer 2

Consecutive integers are separated by 1.. such as 1, 2, 3

Call them: x, x+1, x+2

These sum to 63 so..

x + x + 1 + x + 2 = 63

3x + 3 = 63

3x = 60

x = 20

20, 21, 22
