$243, 81, 27, 9, 3$ $243,81,27,9,3$

Explanation:

The terms in a $geometric sequence$ $color(blue)"geometric sequence"$ are.

$a,ar,ar^2,ar^3,......,ar^(n-1)$

To obtain any term in the sequence, multiply the previous term
by r

$a_1=243$

$rArra_2=243xx1/3=81$

$rArra_3=81xx1/3=27$

$rArra_4=27xx1/3=9$

$rArra_5=9xx1/3=3$
