Answer 1

The Correct Option is A

Step 1: Analyse options.
- The pattern alternates between adding 10% and subtracting 10%. - $10000 + 10\% (1000) = 11000$ - $11000 - 10\% (1100) = 9900$ - $9900 + 10\% (990) = 10890$ - $10890 - 10\% (1089) = 9801$ - $9801 + 10\% (980.1) = 10781.1$ (rounded to 10781).
Step 2: Conclusion.
The next term is 10781. Final Answer: (a) 10781
