Answer 2

Answer:

The next number should be 2100.

Step-by-step explanation:

Consider the provided series.

10, 40, 140, 420, 1050, ?​

We need to find the next term in the series.

Observe the pattern.

10×4=40

40×3.5=140

140×3=420

420×2.5=1050

By applying the above pattern we can find the next term of the series.

1050×2=2100

Hence, the next number should be 2100.
