The series is a sequence of three numbers, the second number is 3 greater than the first, and the third number is 5 greater than the second. (or 8 greater than the first) 20 + 3 = 23 : 23 + 5 = 28 14 + 3 = 17 : 17 + 5 = 22 11 + 3 = 14........is therefore the next number in the sequence.

23\24 19\24 5\8

Each part equals -19. 0-19=-19, 4-23=-19,...so 25-X=-19. This means 25+19=X, so the missing number is 25+19 which is 44.
