Ans: 25 26 Reasoning: read every second number. From first number: 30 29 28 27 26 __(pattern of -1). From second number: 21 22 23 24 25 __(pattern of +1)
13 18 16 21 19 24 22 27 25 ... . This series consists of adding 5 to the first number and subtracting 2 from the next number, repeating the sequence in that order.
