Answers:

1. 2
The given series is
×2+1, ×2+2, ×2+3, ×2+4, ...

2. 5
The given series is ÷2 -6
Reqd no. = 50 ÷ 2 - 6 = 25 - 6 = 19

3. 3
The given series is
×1+1, ×2+2, ×3+3, ×4+4, ×5+5, ×6+6 is

4. 4
(1015 + 1) ÷ 2 = 508;
(508 + 2) ÷ 2 = 255; (255 + 3) ÷ 2 = 129;
(129 + 4) ÷ 2 = 66.5; (66.5 + 5) ÷ 2 = 35.75;
(35.75 + 6) ÷ 2 = 20.875
