Question

The sum of three consecutive even number is 138 , find the greatest of these number​

Answer 1

Answer:

Step-by-step explanation:

X+X+1+X+2=138

3X+3=138

3X=135

X=135/3

X=45

X+1=46

X+2=47

Answer 2

Answer:

The greatest of three consecutive no. is 48

Step-by-step explanation:

Let three consecutive even no's are x, x+2, x+4

It is given that sum of three consecutive even no's = 138

So, x + ( x+2 ) + (x+ 4) =138

     x+x+x+x2+4 =138

            3x + 6 =138

             3x= 138 - 6

            3x= 132

              x= 132/ 3

              x= 44

Greatest no.= x+4

Putting the value of x we get,

Greatest no .=44+4= 48
