Question

find three consecutive positive even integers whose sum is 186

Answer 1

Let the three consecutive numbers be x, x+2, x+4.

x+x+2+x+4= 186

3x+6= 186

3x= 186-6

3x= 180

x= 180/3

x= 60

Answer: The first number is 60.

The second number is 60+2= 62.

The third number is 60+4= 64.

Hope it helps! :)

Answer 2

Let one of the even nos. be x.so, other nos. are x+2 and x+4.
we have,x+(x+2)+(x+4)= 186
⇒3x + 6 = 186 ⇒ 3x = 180 
⇒ x = 60 
∴ The three consecutive even nos. are,x= 60,x+2 = 62, andx+4 = 64
