Answer 2

Answer:

Wrong number = 14

Step-by-step explanation:

1) 12-15= +3

15-20= +5

20-27= +7

27-36= +9

(Check first number difference with third number and third number with fifth and so on..)

there is series of +3,+5,+7,+9

2) 19-17= -2

17-15= -2

15-14= -1

(Check second number difference with fouth number and fourth number with sixth and so on..)

there is series of -2

BUT SERIES IS ODD AT THE POINT OF 14

THERE SHOULD BE 13

15-13 = -2

13-11= -2

SO 14 IS ODD/WRONG
