Answer»

2*3=6

6*3=18

18*3=54

Thus we can conclude that the ratio of any term with the previous term is 3.

The first term of this series is 2

The second term of this series is 2*3

The third term of this series is 2*3*3

Thus we can write the general term of this series nth term=2*(3^(n-1))

so putting 8 in place of n we get

2*(3^7)=4374

P.S. this type of series is called ageometric progression.
