Question

find three consecutive even no. whose sim sum is 234

Answer 1

You know that consecutive means line Wise. so.

(x) + (x+2) + (x+4) = 234

by opening brackets

x  + x + 2 + x + 4 = 234

x + x + x + 2 + 4 = 234

3x + 6 = 234

3x = 234 - 6

3x = 228

x = 228/3

x = 76

so, First number = x  

= 76 

Second number = x + 2

= 76 + 2

= 78

Third number = x + 4
= 76 + 4
= 80

you can see , that. 76 + 78 + 80

= 234

so, three consecutive numbers are 76, 78 and 79.

Answer 2

hi

aim : Find three consecutive even no. whose sim sum is 234

let one number be x

other 2

x +2 and x+4

now lets form an equation 

x  + x + 2 + x + 4 = 234


x + x + x + 2 + 4 = 234

3x + 6 = 234

3x = 234 - 6


3x = 228
x = 228/3
x = 76


so, First number = x  

= 76 


Second number = x + 2
= 76 + 2 
= 78

Third number = x + 4

= 76 + 4

= 80

so the numbers are 76,78,80

hope it helps u
