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
