malfutka [58]

362881

The right sequence should be

2,3,7,25,121,721,5041,40321, 362881

Here, the formula used is a(n)=n!+1 where n=1 to infininity

n(1) =2=1!+1=2

n(2)= 3=2!+1=3

n(3)=7=3!+1=7

n(4)=25=4!+1=25

n(5)=121=5!+1=121

n(6)=721=6!+1=721

n(7)=5041=7!+1=5041

n(8)=40321=8!+1=40321

n(9)=362881=9!+1=362881
