Find the tenth term of the geometric sequence, given the first term and common ratio.

Natalija [7]

Answer:

$a_{10}=\dfrac{1}{128}$

Step-by-step explanation:

In the geometric series:

$a_1=4\\ \\r=\dfrac{1}{2}$

The nth term of the geometric sequence can be calculated using formula

$a_n=a_1\cdot r^{n-1}$

In your case, n = 10, then

$a_{10}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^{10-1}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^9\\ \\=2^2\cdot \dfrac{1}{2^9}\\ \\=\dfrac{1}{2^{9-2}}\\ \\=\dfrac{1}{2^7}\\ \\=\dfrac{1}{128}$

The sum of the squares of their ages is; 5x²

<h3>How to Solve Algebraic Word Problems?</h3>

We are told that Maria is twice the age of Miriam.

Now, of the age of Miriam is x, then we can say that;

Age of Mariam = x

Age of Maria = 2x

Now, we want to find the sum of the squares of their ages. Thus, this is expressed as;

x² + (2x)²

= x² + 4x²

= 5x²
