Question

34. If 440 is the sum of square of three
consecutive even numbers, then find the
middle number.
(A) 12
(C) 14
(B) 10
(D) 16​

Answer 1

Step-by-step explanation:

let the consecutive numbers be x,x+2,x+4 respectively

hence by given condition

x + (x + 2) + (x + 4) = 42

3x + 6 = 42

3(x + 2) = 42

x + 2=42/3

x + 2=14

x = 12

therefore the numbers are

x=12

x+2=12+2=14

x+4=12+4=16

and therefore the middle number is 14
