Answer 1

Answer:

The sum of three numbers is 12

Step-by-step explanation:

Let us take the three consecutive numbers be x, x+1 and x+2.

Given the sum of the last two numbers is equal to the 3 - times

the first number

x+1+x+2=3x

2x+3=3x

x=3

The numbers are 3,4,5.

The sum of three numbers =3+4+5=12
