Final answer:
To find the 5th term of a geometric sequence, use the formula: an = a1 * r^(n-1), where a1 is the first term and r is the common ratio. Plug in the values of a1 and r to find the 5th term.
Step-by-step explanation:
To find the 5th term of a geometric sequence, we need to know the first term (a1) and the common ratio (r). The formula to find the nth term of a geometric sequence is given by an = a1 * r^(n-1). Therefore, to find the 5th term, we plug in the values of a1 and r into this formula.
Let's say the first term is 2 and the common ratio is 3. Plugging these values into the formula, we have a5 = 2 * 3^(5-1). Simplifying this expression gives us a5 = 2 * 3^4 = 2 * 81 = 162.
