${8, 24, 72, 216, 648, 1944, 5832, 17496, 52488, 157464, 472392, 1417176}$ ${8,24,72,216,648,1944,5832,17496,52488,157464,472392,1417176}$

I am assuming that this is a geometric sequence in the form:

$a,ar,ar^2,ar^3...$

We know that:

$a_1=8$

$r=3$

We multiply by $3$ to get to the next term.

$8=>24=>72=>216=>648=>1944=>5832=>17496=>52488=>157464=>472392=>1417176$

The answer is ${8,24,72,216,648,1944,5832,17496,52488,157464,472392,1417176}$
