Answer:

x = 4

Step-by-step explanation:

You may want to make everything into the same fraction to make the math easier. Because x/4 is the smallest fraction, make all of the other numbers with x match it.

3x = 12x/4, x/2 = 2x/4.

Now, 12x/4 - x/4 = 11x/4.

11x/4 + 9 = 1 - 2x/4 - 5. Now add x to one side to solve x.

13x/4 +9 = 1 - 5

13x/4 + 9 = -4

13x/4 = -13 (multiply by four on each side)

13x = -52

x = 4

Find the first four terms of the recursive sequence defined by the following formula: an = an-1 4 where a4 = 2 1 4 , , , 2 1 4.

Elina [12.6K]

The first four-term of the sequence is found by the given equation $a_{n-1} = 4a_n$ is given as 144, 36, 9, and 9/4.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The given equation will be

$\rm a_n = \dfrac{a_{n-1}}{4} \\\\a_{n-1} = 4a_n$

And

$a_4 = 2 \dfrac{1}{4} = \dfrac{9}{4}$

For n = 4, we have

$\rm a_{4-1} = 4a_4\\\\a_3 \ \ \ = 4*\dfrac{9}{4} \\\\ a_3 \ \ \ = 9$

For n = 3, we have

$\rm a_{3-1} = 4a_3\\\\a_2 \ \ \ = 4*9 \\\\ a_2 \ \ \ = 36$

For n = 2, we have

$\rm a_{2-1} = 4a_2\\\\a_1 \ \ \ = 4*36 \\\\ a_1 \ \ \ = 144$
