Question

In the following question, a number series is given, after the number series, a number and then A, B, C, D and E are given. Compete the number series starting from the given number based on the pattern of the original number series and choose correct option.

9	15	90	95	475	479	1916
8	A	B	C	D	E	F

 

What will come in place of ‘D’?

1. 475
2. 479
3. 465
4. 454
5. 445

Answer 1

Correct Answer - Option 5 : 445

The pattern of the given series is as follows:

9 + 6 = 15

15 × 6 = 90

90 + 5 = 95

95 × 5 = 475

475 + 4 = 479

479 × 4 = 1916

Now, the series on the same pattern starting from 3 would be,

⇒ A = 8 + 6 = 14

⇒ B = 14 × 6 = 84

⇒ C = 84 + 5 = 89

⇒ D = 89 × 5 = 445

∴ The number in place of D is 445.
