Answer 2

Answer:

The next number in the given series is 21600.

Step-by-step explanation:

The given series is

900 1800 5400

From the given series it is clear that the series in the form of

$a_n=(a_{n-1})n$

Where, a1=900.

$a_2=(a_{2-1})2=(a_1)2=(900)2=1800$

$a_3=(a_{3-1})2=(a_2)3=(1800)3=5400$

The next number in the series is

$a_4=(a_{4-1})2=(a_3)4=(5400)4=21600$

Therefore the next number in the given series is 21600.
