Answer:
3
Step-by-step explanation:
a5 = a* r^4 ( from general formular of a GP)
= 243 * (1/3)^4 =. 243 * 1/81 = 3
The required 5th term in the geometric sequence is 3.
For geometric sequence a = 243 and r = 1/3.
fifth term to be determine.
Geometric progression is sequence of series whose ratio with adjacent values remains same.
Here, a = 243 and r = 1/3.
fifth term = [tex]ar^{n-1}[/tex]
= [tex]243*(1/3)^{5-1}[/tex]
= [tex]243*(1/3)^4[/tex]
= 243 * 1/81
= 3
Thus, the required 5th term in the geometric sequence is 3.
