ReplyDeletewhy post same thing multiple time...

Delete1*1 + 1=2

ReplyDelete2*2 + 2=6

6*3 + 3=21

21*4 + 4=88

88*5 + 5=445

@prabakar sir...i think that this might take some time to find out the way..

ReplyDeleteanother solution:

ReplyDelete1*(1+1)=2

2*(2+1)=6

3*(6+1)=21

4*(21+1)=88

5*(88+1)=445
