``````1,1,2,3,8,.....
``````

1*1 = 2
1*2 = 2+1 = 3 `1st No=1`
2*3 = 6+2 = 8 `1st No=2`
3*8 = 24+3 = 27 `1st No=3`

``````1,1,2,3,8,**27**,......
``````

8*27 = 216+8 = 224 `1st No=8`

``````****1,1,2,3,8,27,224,.............****

1st term = 1
2nd term = 1st term × no term {1} + 0th term = 1
3rd term = 2nd term × 1st term {1} + 1st term = 2
4th term = 3rd teem × 2nd term {2} + 2nd term = 3
5th term = 4th term × 3rd term {6} + 3rd term = 8
Therefore 6th term = 8×3 + 3 = 27 answer Feb 18, 2016

1*0 + 1 = 1
1*1 + 1 = 2
