Question 55496
The sum of three consecutive integers is 42


Show equation.
When we count we are counting by adding 1's:
1,1+1,1+1+1,1+1+1+1,...=1,2,3,4,...
Therefore, 
Let the 1st integer be:x
Then the 2nd integer is: x+1
Then the thrid integer is: x+1+1=x+2
Sum means add:
(x)+(x+1)+(x+2)=42
x+x+1+x+2=42
3x+3=42
3x+3-3=42-3
3x=39
3x/3=39/3
x=13
The 1st integer is:x=13
The 2nd integer is:x+1=13+1=14
The 3rd integer is: x+2=13+2=15
:
Check, does 13+14+15=42?
Yes, we're right!!!
Happy Calculating!!!
