Question

What will be the next number in the series: 3, 6, 10, 17, 26, ?

• A. 38
• B. 39
• C. 40
• D. 41

Answer 1

The Correct Option is A

Step 1: Analyze the series: 
The differences between consecutive numbers are: 6 - 3 = 3, 10 - 6 = 4, 17 - 10 = 7, 26 - 17 = 9 
The differences themselves form the sequence: 3, 4, 7, 9. 
Step 2: Predict the next difference: 
The pattern alternates between adding 1 and adding 3. 
The next difference will be 9 + 3 = 12. 
Step 3: Add this difference to the last number: 
26 + 12 = 38
