Answer 1

9 2 22 3 7 20 11 7 36

Answer 2

Answer:7

Step-by-step explanation:

here the series is some logical. so i am explaining the logic of given series. series is divided in each three terms where third digit is double the value of sum of first two digits.

(9+2)*2=22

(3+7)*2=20

similarly,

(11+x)*2=36

⇒11+x=18

⇒x=7

so at the place of question mark put 7 and complete the series.
