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. Complete the number series starting from the given number based on the pattern of the original number series and choose correct option. 6 18 54 162 486 1456 15 A B C D E   What will come in place of ‘A’? Correct Answer 45

The pattern of the original number series is

⇒ 2 × 3 = 6

⇒ 6 × 3 = 18

⇒18 × 3  = 54

⇒ 54 × 3 = 162

⇒  162 × 3 = 486

⇒ 486 

× 3 = 1456

According the pattern of the above series the number series starting from the given number 15 would be as:

 

⇒15

⇒ A = 15 × 3 = 45

⇒ B = 45 × 3 = 135

⇒ C = 135 × 3 = 405

⇒ D =405 × 3 = 1215

⇒ E = 1215 × 3 = 3645

∴ The required number in place of E would be 3645
