The sum of three consecutive numbers is 537. What is the 3rd number?

For this problem your equation will be x + (x+1) + (x+2) = 537

Multiply and Simplify:

x+x+1+x+2=537

3x+3=537

Subtract 3 from both sides:

3x+3-3=537-3

3x=534

Divide both sides by 3:

3x/3=537/3

x=179

179 is the middle number so: 178+179+180=537

180 is the third number.
