The sum of two consecutive even numbers is 38. Find the numbers.
➣ The sum of two consecutive even numbers = 38
➣ The two consecutive even numbers
➪ Let, the first consecutive even number = x
➪ Let, the second consecutive even number = x + 2
⇒ x + x + 2 = 38
⇒2x + 2 = 38
⇒2x = 38 - 2
⇒2x = 36
⇒x =
⇒ x = 18
⟼ The First Consecutive Even Number = x = 18
⟼ The Second Consecutive Even Number = x + 2 = 18 + 2 = 20
➦ The two consecutive even numbers whose sum is 38 are 18 and 20.
Given: The sum of two consecutive even numbers is 38.
To Find : the numbers.
Solution:
Assume that 2 consecutive even numbers are
2n , 2n + 2
Sum of two consecutive even numbers is 38
=> 2n + (2n + 2) = 38
=> 4n + 2 = 38
=> 4n = 38 - 2
=> 4n = 36
=> n = 9
2n = 2 (9) = 18
2n + 2= 18 + 2 = 20
Two consecutive even numbers whose sum is 38 are 18 and 20
