Step-by-step explanation:
<u>Arithmetic Sequences
</u>
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:

Answer: D
Answer:
42
Explanation:
Using Order of Operations, we have to evaluate the exponent first:
27 + 6(2 + 3/6)
Simplifying the fraction, we have:
27 + 6(2 + 0.5)
Add the values inside the parenthesis:
27 + 6(2.5)
Multiply:
27 + 15
Add:
42
Answer:
The correct option is <u>$2.50</u>.
Step-by-step explanation:
This can be determined by calculating the change in total cost of lunch using the data given in the question as follows:
Slice of pizza Total cost of lunch ($) Change in total cost of lunch ($)
0 7.5 -
1 10 2.5
2 12.5 2.5
3 15 2.5
4 17.5 2.5
5 20 2.5
6 22.5 2.5
7 25 2.5
8 27.5 2.5
Since the change in total cost of lunch in table abov is constant at $2.50, this implies that for each additional slice of pizza that is purchased, the total cost of lunch increases by $2.50.
Therefore, the correct option is <u>$2.50</u>.
