Question

Dont pay attention to this part i put all the detail at the summarry of my question

 

Answer 1

Three consecutive numbers are:

n, n + 1, n + 2

 

n + n + 1 + n + 2 = 144       combine like terms

3n + 3 = 144                       subtract 3 form both sides

3n = 141                             divide both sides by 3

n = 47

 

The smallest number is forty-seven.
