spayn [35]

Triangle WXZ and triangle XZY are similar triangles by the side angle side similarity postulate, therefore 16/12 = 12/9.

<h3>What are similar triangles?</h3>

Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. Also, their corresponding angles are congruent.

Triangle WXZ and triangle XZY are similar triangles by the side angle side similarity postulate, therefore 16/12 = 12/9.

Given that aₙ = (-2) (5)ⁿ⁻1 for a geometric sequence, determine the common ratio:

patriot [66]

Answer:

Step-by-step explanation:

The nth term of the geometric sequence is

$a_n=(-2)(5)^{n-1}$

In general the nth term of a geometric sequence is

$a_n=a_1(r)^{n-1}$

By comparism;

$r=5$ is the common ratio of the sequence.

$a_1=(-2)(5)^{1-1}=-2$

$a_2=(-2)(5)^{2-1}=-10$

Common ratio is

$r=\frac{-10}{-2}=5$
