what is the nth term of the geometric sequence that has a common ratio of 6 and 24 as its third term?
Common ratio, r= 6
3rd term=24
Finding first term=
24=a\(6^{2}\)
24=36a
a=24/36
a=2/3
nth term=\(2/3(6)^{n-1}\)
Answer:
The nth term of the series is
\(a_n=\frac{2}{3}\cdot 6^{n-1}\)
Step-by-step explanation:
Given: Third term = 24 and r = 6
We are given third term and common ratio of geometric series.
Formula:
\(a_n=a\cdot r^{n-1}\)
For third term, n=3 and r=6
\(a_3=a\cdot 6^{3-1}\)
\(24=a\cdot 36\)
\(a=\frac{2}{3}\)
We need to find nth term of the series
\(a_n=\frac{2}{3}\cdot 6^{n-1}\)
Hence, The nth term of the series is \(a_n=\frac{2}{3}\cdot 6^{n-1}\)
