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

3 = 2 * 1 + 1
8 = 3 *2 + 1 + 1
28 = 8 * 3 + 2 + 1 + 1

28 (Multiply last two digits and add remaining ones)

1*1 = 2
1*2 = 2+1 = 3
2*3 = 6+1+1 = 8
3*8 = 24+2+1+1 = 28
