Answer:

The expression that represents the given sequence is 5+6(n-1). Option C (not labeled).

Explanation:

<u>Arithmetic Sequences</u>

In an arithmetic sequence, each term can be obtained by adding or subtracting a fixed number to the previous term. That fixed number is called the common difference.

We are given the following sequence:

5, 11, 17, 23, 29, ...

Each term is located in a position starting from n=1. Let's test each option:

A For n=1 we should have the first term (5). Substituting n=1 into the general equation: 5+6(n+1) = 5+6(1+1) = 5+12 = 17. Since the resulting term is not 5, this option is incorrect.

B For n=1, 6+5(n+1)= 6+5(2)=16. This option is incorrect.

C (not labeled) For n=1, 5+6(n-1)=5+6(1-1)=5+0=5. The first term is correct. Let's test for the second term (n=2):

5+6(2-1)=5+6=11. Correct. For n=3

5+6(3-1)=5+12=17. Correct.

We can see the terms are increasing by 6, and the given sequence is also increasing by 6. Thus, This option is correct.

D For n=1, 6+5 (n-1)=6+0=6. This option is incorrect.

A sequence of numbers begins with 12 and progresses geometrically. each number is the previous number divided by 2. which value

Since <span>each number is the previous number divided by 2, the common ratio 1/2. The common ratio can be solved by dividing the number by the previous number. </span>

What is the ration between 28000 and 14?

r-ruslan [8.4K]

The ratio between 28,000 and 14 is 2000 : 1

<h3>How to determine the ratio?</h3>

The numbers are given as:

28,000 and 14

Express as ratio

Ratio = 28000 : 14

Divide each number by 14

Ratio = 2000 : 1
