Solution:

5*2 = 10.
4*10 = 40.
3*40 = 120.
2*120 = 240.
1*240 = 240.

@Usha

The given series : 240, ??? , 120, 40, 10, 2

We have to find the element at the place of '???'. So,

Initial = 240
240/1 = 240 <-- This is the required answer.
240/2 = 120
120/3 = 40
40/4 = 10
10/5 = 2.

[or]

Do it in the reverse order.

Initial value = 2
2 x 5 = 10
10 x 4 = 40
40 x 3 = 120
120 x 2 = 240 <-- This is the required answer.
240 x 1 = 240.

Hope this help you. Have a nice day!
