1.	Find the odd pair of numbers.1. 10 - 202. 12 - 253. 15 - 314. 9 - 19
Answer» Correct Answer - Option 1 : 10 - 20 The logic followed is: The second number = (First number × 2) + 1 Option 1 → 10 - 20 20 = 10 × 2 + 1 20 = 20 + 1 20 ≠ 21 Option 2 → 12 - 25 25 = 12 × 2 + 1 25 = 24 + 1 25 = 25 Option 3 → 15 - 31 31 = 15 × 2 + 1 31 = 30 + 1 31 = 31 Option 4 → 9 - 19 19 = 9 × 2 + 1 19 = 18 + 1 19 = 19 Hence, the correct answer is "Option 1".

Answer» Correct Answer - Option 1 : 10 - 20

The logic followed is:

The second number = (First number × 2) + 1

Option 1 → 10 - 20

20 = 10 × 2 + 1

20 = 20 + 1

20 ≠ 21

Option 2 → 12 - 25

25 = 12 × 2 + 1

25 = 24 + 1

25 = 25

Option 3 → 15 - 31

31 = 15 × 2 + 1

31 = 30 + 1

31 = 31

Option 4 → 9 - 19

19 = 9 × 2 + 1

19 = 18 + 1

19 = 19

Hence, the correct answer is "Option 1".
