<u>Arithmetic Sequences</u>
The arithmetic sequences are identified because 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 first terms of a sequence:
-12, -28, -44,...
Find the common difference by subtracting consecutive terms:
r = -28 - (-12) = -16
r = -44 - (-28) = -16
The first term is a1 = -12. Now we calculate the term n=61:



Answer:
The answer is A) Round 56 to 60, find 10%, then double.
Step-by-step explanation:
You would round to 60 because 56 is closer to 60 than 50 then 10% is half of 20% so you would double it after you found 10% of 60.

Answer:
Elevator 1 is 16 feet above ground level, and elevator 2 is 25 feet below ground level
Step-by-step explanation:
Elevator one is moving up, so it means it's above ground level since it started on the ground
Elevator is moving negative floors, so it is moving below.
