​

Answer 1

Answer:

Three consecutive integers add up to 51. What are these integers? Let consecutive numbers be, x, x+1 and x+2. Thus, the required three consecutive 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
