Question

The sum of three consecutive integers is 51. Find the largest number.

Answer 1

Answer:

the largest number is 18

Step-by-step explanation:

let the three consecutive integers are X,X+1,X+2

the sum of three consecutive integers are

x+(X+1)+(X+2)=51

x+x+X+1+2=51

3x+3=51

3(X+1)=51

x+1=51÷3

x+1=17

x=17-1

x=16

the first number is X=16

the second number is X+1=16+1=17

the third number is X+2=16+2=18

the largest number is 18
