Enter a recursive rule for the geometric sequence.

Jlenok [28]

Answer:

$x_{n} = 5 \ * \ (-2)^{n-1}$

Step-by-step explanation:

Given the geometric sequence:

5, −10, 20, −40, ...

The first term is a = 5

And the common ratio = r = -10/5 = -2

The general rule of geometric sequence is

$x_{n} = a \ * \ r^{n-1}$

So, the rule for the given geometric sequence is:

$x_{n} = 5 \ * \ (-2)^{n-1}$

Answer:

OPTION B - 25

Step-by-step explanation:

We know that:

$(a^x)^y = a^{x . y}$

$\frac{a^x}{a^y} = a^{x - y}$

$a^x . a^y = a^{x + y}$

The given problem uses these results to arrive at the answer.

$(5^2)^{-3} = 5^{2 . (-3)} = 5^{-6}$

Now, $5^{-6 + 4} = 5^{-2}$

Now, $\frac{5^{-2}}{5^{-4}} = 5^{-2 -(-4)} = 5^{(-2 + 4)} = 5^2$

⇒ 5² = 25.

∴ The answer is 25. (Option B)
