Question

B
12) The sum of three consecutive even natural numbers is 48.
Find the greatest of these numbers.​

Answer 1

Answer:

Let us assume the three consecutive even numbers of series to be:x,x+2 and x+4.

So, the sum of the consecutive even numbers = 48=x+x+2+x+4

⇒48=3x+6

⇒−3x=6−48

⇒−3x=−42

⇒x=14

Therefore, three consecutive even numbers are,

x=14

x+2=14+2=16

x+4=14+4=18

So, greatest of these number is 18

Answer 2

Answer:

The greatest no. is 17

Step-by-step explanation:

Let the first number be $x$

Let the second no. be $x+1$

Let the third no. be $x+2$

A.T.Q.

$x+x+1+x+2=48$

$3x+3=48$

$x=15$

Third no.$=15+2=17$
