Answer 2

Heya........!!!

___________________________


If we see carefully It's a series

=> add first 2 number and then multiply it by 2 .

=> 9 + 4 = 13 •--» 13 × 2 = 26

=> 9 + 16 = 25 •--» 25 × 2 = 50


Similarly :-

=> 16 + x = 40 / 2 ( divided by 2 as we multiply the sum by 2 )

=> 16 + x = 20
=> x = 20 - 16


→ x = 4 is the answer .
