- The given series is 1, 11, 99, 693, 3465, ?

- Consider the pattern: multiply each number by an increasing factor:

- \(1 \times 11 = 11\)

- \(11 \times 9 = 99\)

- \(99 \times 7 = 693\)

- \(693 \times 5 = 3465\)

- Option 2: 11296 - Does not fit the pattern.

- Option 3: 10395 - Fits the pattern perfectly

- Option 4: 12974 - Does not fit the pattern.
