Answer 2

Hi there !

Here's your answer

in the first pattern,
given,

4 - 4 - 7

you can see that if you add up 4 and 4 and subtract 1 from the sum, you will get 7

i .e

4 + 4 - 1 = 7

this can be observed in the second puzzle also,

given

7 - 7 - 13

= 7 + 7 - 1 = 13

similarly,

5 + 5 - 1 = 9


hence 9 is the answer
