What is the formula for a Arithmetic series and how can you use it in a practical situation? Show explanation!

SVETLANKA909090 [29]

A finite geometric series is that where the consecutive terms have a fix ratio.

Call r the ratio, An the nth term and An+1 the next term to n, then:

An+1 / An = r

For example, the geometric series, 1, 3, 9, 27, 81, ..

You can verify that

3 = 1* 3

9 = 3 * 3

27 = 9 * 3

81 = 27 * 3

So, the formula is An+1 = An * r, so if you know the first term you can find any other term.

For example, Find the fifth term of a geometric series where the first term is 5 and the second term is 25.

r = second term / first term = 25 / 5 = 5

=> Fifth term = First term * r * r * r * r = First term * r^4 = 25 * 5^4 = 15,625

From this you can also see this valid formula:

An = A1 * r^ (n-1).

So now you have two equivalent formulas:

An+1 = An * r, which is called recursive formula, and

An = A1 * r ^ (n-1), which is called explicit formula

hope this helps :)

5 race to the power 5 is what <br>..

bonufazy [111]

Answer:

To find the answer, you multiply 5 by itself 5 times as follows: 5 x 5 x 5 x 5 x 5 =. And you get the answers which is. 3,125. Note that 5 to the power of 5 is the same as 5 raised to 5. In x y, 5 is the base (x) and 5 is the exponent (y) and you can therefore also write the problem and the answer as follow: 5 5 = 3,125.

Step-by-step explanation:

Pls need help to Divide 40x/64y by 5x/8y

Stolb23 [73]

<h3>Answer:</h3>

<h3>Step-by-step explanation:</h3>

The first fraction reduces to 5x/(8y), identical to the second fraction. When something is divided by itself, the result is 1.
