Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 125, 25

Igoryamba

Answer:

Given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

125, 25, 5, .. ..

Here

$a_1 = 125\\a_2 = 25\\a_3 = 5$

A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.

A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.

Finding the common ratio

$r = \frac{a_2}{a_1} = \frac{125}{25} = 5\\r = \frac{a_3}{a_2} = \frac{25}{5} = 5$

As we can see that the common ratio is same, the given sequence is a geometric sequence.

Solve the following equation, answer as a reduced, mixed number. 4(3 - 2x) = 15

Inessa05 [86]

Start by distributing the 4:
12-8x=15
Add 8x to both sides of the equation and subtract 15 from both sides:
8x=-3
divide both sides by 8 to get the value of x:
x=-3/8
