Question

What comes in place of the question mark (?) in the series given below:

B2D, C3F, E5J, G7N, ?

Accepted Answer

#### Step 1: Analyze the Pattern
The series involves three components: **letters**, **numbers**, and **letters**. Let’s break it down:

1. **First Letter**:  
   The alphabet sequence increases by 1 step at each term:  
   $$ B 	o C 	o E 	o G 	o I $$.

2. **Number**:  
   The numbers increase by 2 at each step:  
   $$ 2 	o 3 	o 5 	o 7 	o 9 $$.

3. **Third Letter**:  
   The alphabet sequence increases by 2 steps at each term:  
   $$ D 	o F 	o J 	o N 	o R $$.

#### Step 2: Find the Missing Term
Using the identified patterns:  
- First letter = **I** (after G).  
- Number = **9** (after 7).  
- Third letter = **R** (after N).

Thus, the missing term is **I9R**.

Therefore, the correct answer is **1. I9R**.
