@Jai Gupta you should try some more difficult and interesting questions. Posting these MAT series will not help you in getting popular. And your followers will also not increase by this.
But the second term in the (modified) series is 40, not 41.

Seeee What i had done is
Subtract -1 from allll
Then new series is 4 ,40, And so on
Then pattern you can see above
Before i had done -1 Thats why i had done +1
Calvin if dont understand this tell me ill delete this problem as it is becoming contoversial

Yes, I understand that you "subtract 1 from all". This gives us the sequence:
4 , 4 0 , 3 2 1 , 1 9 2 0 , 7 6 8 0 , 1 5 3 6 0
Can you explain (again) what the rule is to get this sequence?
It seems to me that you want a i + 1 = a i × ( 1 2 − 2 i ) + 1 , but this will give a 2 = 4 × 1 0 + 1 = 4 1 instead of 41.
I'm guessing that your original sequence should have been
5 , 4 2 , 3 2 1 , 1 9 2 1 , 7 6 8 1 , 1 5 3 6 1

@Calvin Lin – Calvin your series is wrong in place of 321 there should be 320 in your first series And yahh satvik will talk about this problem I call him and told about this

@Jai Gupta – Ah, I see the reason for my confusion.
In your solution, can you change "321" to "320"? Also, in your explanation, remove the "+1" part of it. You are describing the 2nd series, and not the first series.

To my comment below in this solution, which states "But the second term in the (modified) series is 40, not 41"
-1 from all
series become like this 4 , 40 , 321, 1920 , 7680 , 15360
4 multiplied by 10 =40+1=41
40 multiplied by 8 =320+1=321
similarly same is applied
15360 multiplied by 0 =0+1=1
