How much is the next? It's better to have a general formula! 32144680, the following numbers are required

Find the rules:
eight
8*5-8*(0*0+1)=32
32*5-8*(1*1+1)=144
144*5-8*(2*2+1)=680
680*5-8*(3*3+1)=3320
So the answer should be 3320
The rules are as follows: (n is the number)
The nth number = the previous number * 5-8 * [(n-2) * (n-2) + 1]
---------------------------------------------
I found it myself,
So I don't know, right
But at the very least,
It is suitable among the four numbers
Too few figures!
