Which of the following sequences of numbers are arithmetic sequences?

An arithmetic sequence is a sequence of numbers with a common difference. 

In the choices above, only A and D are arithmetic sequences. 

<em>In A, the common difference is 2 while in D, it's 0 .1. 
</em>

B can't be an arithmetic sequence since the number 1 is just being repeated many times, there's no progression.

C as well. Be observant of the pattern, it can be an arithmetic sequence only if it has 4 before 5. 

E obviously is not an arithmetic sequence. If you try to find the difference between the consecutive terms, it's not common.

Sylvie bought 13 bagels and a container of cream cheese.Each bagel cost the same price.The cream cheese cost $2.95.Sylvie spent
Taya2010 [7]
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50 <u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

7.50=2.95+13(b)

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as 

4.55=13 (b)

Now, to get "b" by itself, you must divide 13 on both sides, resulting as

.35=b

This will answer your question as the cost of 1 bagel would be $0.35 per bagel.

The "Let's Roll" game uses a number cube with the numbers 2,4,6,8,10, and 12. There are prizes for rolling any number less than
deff fn [24]
There is a 33.3% chance of rolling a number less than 6. It’s 2/6, which is reduced to 1/3. = that to x/100, multiply 1 x 100, and divide that by 3. So it’s 100 divided by 3, and that’s 33.3, which is the percentage.

Find the common difference for the infinite arithmetic sequence shown.
mihalych1998 [28]

The common difference is 12

Further explanation:

It is given that the infinite sequence is an arithmetic sequence

The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

a_1 = 211\\a_2 = 223\\a_3 = 235\\a_4 = 247........

The common difference is denoted by d.

Here,

d = a_2-a_1 = 223-211 = 12\\a_3-a_2 = 235-223 = 12

The common difference is same for all proceeding terms.

So,

d = 12
