Question

What is the next number in the series given below?
\(11, 12, 26, 81, 328, ?\)

• A. 1375
• B. 1485
• C. 1540
• D. 1645

Answer 1

The Correct Option is D

Let’s analyze the pattern of the series. We observe that the terms are multiplying by increasing factors and adding a consistent value:

• 11 ×1+1=12
• 12 ×2+2=26
• 26 ×3+3=81
• 81 ×4+4=328

Following this pattern for the next term:

328 ×5+5=1645

Conclusion: Thus, the next number in the series is 1645
