Question

The sum of 3 consecutive integers is 45.What are these integers?

Answer 1

3x +3=45
3x=45-3,
3x=42
x=42/3
x=14

Answer 2

Let the first number be x
The other two numbers will be x + 1 and x + 2

According to question
x + (x + 1) + (x + 2) = 45

Solve the above equation
x + x + 1 + x + 2 = 45
3x + 3 = 45
3x = 42
x = 14

So, the numbers are 14, 15 and 16
