Question:


The missing term in the sequence 7, 11, 19, 31, ______, 67 is 

    (A) 43 

    (B) 47 

    (C) 51 

    (D) 45


Solution:


Let's analyse the pattern:

  • The difference between the terms is as follows:

    • 11−7=4

    • 19−11=8

    • 31−19=12

The differences are increasing by 4 each time.

Following this pattern:

  • The next difference should be 12+4=16.

Adding 16 to the last known term in the sequence:

  • 31+16=47

So, the missing term is 47.

Correct answer: (B) 47
