Question

the average of 3 consecutive even no. is 18 find the largest of these no.
​

Answer 1

Answer:

19

Step-by-step explanation:

let the no be x,x+1,x+2

avg= (x+x+1+x+2)/3=18

3(x+1)=18

x+1= 18

x= 17

largest no = 17+2 = 19

Answer 2

Step-by-step explanation:

Let's take these numbers as x, x+1, x+2

Now, x+x+1+x+2=18

3x+3= 18

3x = 18-5

x=15/3

X = 5

X+1= 5+1 = 6

X+1= 5+1 = 6x+2 = 5+2 = 7
