What should come in place of '?' in the given series?
2 7 22 67 ?

To find the number that should come in place of the question mark (?) in the series, let's analyze the relationship between consecutive terms of the given series:

2, 7, 22, 67, ?

Let's check the difference or the multiplication pattern between the terms:
First term = 2
Second term = 7
Third term = 22
Fourth term = 67

Let's observe the transition from one term to the next:
From 2 to 7:
$2\times 3+1=7$

From 7 to 22:
$7\times 3+1=22$

From 22 to 67:
$22\times 3+1=67$

Following this consistent pattern, each term is obtained by multiplying the previous term by 3 and then adding 1. Let's apply this rule to find the fifth term (?):
$67\times 3+1=201+1=202$

Therefore, the missing number in the series is 202, which corresponds to Option 202.
