Question

5,3,4 =18 ; 3,5,3=65; 9,6,3=?

Answer 1

Given:

• A series 5,3,4 =18; 3,5,3=65; 9,6,3=? is given.

To Find:

• Pattern of the series  and next number of the series.

Solution:

First series is

               $5,3,4 = 18 5^2- (3+4) -0 = 25 - 7 = 18$

Second series is  

             $3,5,3 = 65\\ 3^4 - (5 \times 3) -1 = 81 - 15 - 1 = 65$

for the third series we have to alter the equation on like

So,        $9^2 - (6+3) - 2 = 81-9-2= 7$

Thus, the series is  $9,6,3 = 70$
