Question

Three consecutive integers add up to 51. What are these
integers?​

Answer 1

Answer:

16,17 and 18.

Step-by-step explanation:

Let the numbers be x,(x+1),(x+2).

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

or,x+x+1+x+2=51

or,3x+3=51

or,3x=51-3

or,3x=48

or,x=48/3

or,x=16

Therefore the numbers are 16,17 and 18.

Answer 2

Let the three consecutive integers be x, x+1 and x+2.

According to the question,

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

⇒ 3x + 3 = 51

⇒ 3x = 51 – 3

⇒ 3x = 48

⇒ x = 48/3

⇒ x = 16

Thus, the integers are

x = 16

x + 1 = 17

x + 2 = 18
