B. 25

Here alternate numbers are forming patterns –
Series 1:  106   52   ?   11.5
Series 2: 84   44   24   14
Series 1:
→ 106
→ 52 = (106 – 2) ÷ 2
→ ? = (52 – 2) ÷ 2,
→ 11.5 = (25 – 2) ÷ 2,
Series 2:
→ 84
→ 44 = (84 ÷ 2) + 2
→ 24 = (44 ÷ 2) + 2,
→ 14 = (24 ÷ 2) + 2,
Thus, the missing number is 25
