Question

if the sum of three consecutive even number is 243,then the smallest among them is?​

Answer 1

Let the three consecutive even numbers be 2x−2,2x.2x+2.

We have,

(2x−2)+2x+(2x+2)=234

⇒6x=234

⇒x=39

∴ Least even number is 2x−2=2(39)−2=76.

Hope this answer helps you

Answer 2

Step-by-step explanation:

let the tree consecutive even number be

a-d,a,a+d

according to given condition

a-d+a+a+d=243

3a=243

a=243

3

a=81........(1)

according to second condition

a-d=243

81-d=243.............. (from 1)

-d=243-81

-d=162

d=-162

a=81

a-d=81-(-162)=81+162=243

a+d=81+(-162)=81-162=-81

the smallest among is -81
