1.	What will come in place of question mark (?) in the following number series?28, 34, 46, 66, 96, ?1. 2382. 423. 1384. 1585. None of these
Answer» Correct Answer - Option 3 : 138 Considering the above series, 28, 34, 46, 66, 96, ? The logic of the series can be explained as, 34 – 28 = 6 = 2 × 3 46 – 34 = 12 = 3 × 4 66 – 46 = 20 = 4 × 5 96 – 66 = 30 = 5 × 6 By observing the pattern, ? – 96 = 6 × 7 = 42 ⇒ ? = 42 + 96 ⇒ ? = 138 ∴ The value of ? is 138

Answer» Correct Answer - Option 3 : 138

Considering the above series,

28, 34, 46, 66, 96, ?

The logic of the series can be explained as,

34 – 28 = 6 = 2 × 3

46 – 34 = 12 = 3 × 4

66 – 46 = 20 = 4 × 5

96 – 66 = 30 = 5 × 6

By observing the pattern,

? – 96 = 6 × 7 = 42

⇒ ? = 42 + 96

⇒ ? = 138

∴ The value of ? is 138
