- The series starts with 40 and progresses through 80, 200, 600, and 2100.

- Look for a pattern in the series.

- Each number seems to be multiplied by an increasing factor and then added to an incrementally increasing value.

- 40 multiplied by 2 gives 80.

- 80 multiplied by 2.5 gives 200.

- 200 multiplied by 3 gives 600.

- 600 multiplied by 3.5 gives 2100.

- The pattern involves multiplying by increasing factors: 2, 2.5, 3, 3.5...

- Next factor is 4: 2100 multiplied by 4 = 8400

Option 3, 8400, is correct.
