1.	1). 32). 53). 16 at 5th position4). 15
Answer» 3 = 12 × 0.25 ⇒ 5 = 10 × 0.5 ⇒ 8 = 8 × 1 ⇒ 15 ≠ 6 ×? 2 (not following the logic USED in the series) ⇒ 16 = 4 × 4 ⇒ 16 = 2 × 8 The logic is that the first number is decreasing by value 2 and the number MULTIPLIED to it, is getting doubled after each term. ∴ 15 is the wrong term in the series.

Answer»

3 = 12 × 0.25

⇒ 5 = 10 × 0.5

⇒ 8 = 8 × 1

⇒ 15 ≠ 6 ×? 2 (not following the logic USED in the series)

⇒ 16 = 4 × 4

⇒ 16 = 2 × 8

The logic is that the first number is decreasing by value 2 and the number MULTIPLIED to it, is getting doubled after each term.

∴ 15 is the wrong term in the series.
