An example of 12.1 arithmetic sequences algebra 2 question is Find the sum of the arithmetic series given as 1,2,3…..99,100.
<h3>What is Arithmetic sequences?</h3>
An arithmetic sequence is known to be a group or sequence of numbers that is said to be the difference that exist between any two successive members of the sequence and it is a constant.
To find the sequence, one was given a total of 100 values:
So n=100.
first value = 1
Last = 100.
=100/2 (1+100)= 5050
Therefore the answer is 5050

Answer:
There are no solutions for this equation.
Explanation:
We move all terms to the left:
1/t+1/18-t-(1/4)=0
Domain of the equation: t=0
t∈R
We add all the numbers together, and all the variables
1/t-t+1/18-(+1/4)=0
We add all the numbers together, and all the variables
-1t+1/t+1/18-(+1/4)=0
We get rid of parentheses
-1t+1/t+1/18-1/4=0
We calculate fractions
There is no solution for this equation
Graphs are used to represent functions and equations
<h3>How to determine the graph of the function</h3>
The equation of the function is given as:
f(x)=3sin(x/4+1)-1/2
The above function is a sine function.
So, we make use of the sine graph to represent the function f(x)
Set x = 0.
So, we have:
f(0) = 2.204
This means that, the graph of the function f(x) passes through (0,2.204)
See attachment for the graph of the function

The statement which best explains why carbon bonds to four (4) hydrogen atoms to form methane but to only two (2) oxygen atoms to form carbon dioxide is: Hydrogen shares a single (one) valence electron with carbon while oxygen shares two (2) valence electrons.
A chemical bond can be defined as the forces of attraction that are existing between ions, crystals, atoms or molecules and they are mainly responsible for the formation of chemical compounds.
Hence, a chemical bond refers to a force holding atoms together and binding ions, crystals, or molecules together, in order to form a chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of the atom of a chemical element.
Methane comprises of an atom of carbon and four (4) hydrogen atoms while carbon dioxide comprises of an atom of carbon and two (2) oxygen atoms.
Basically, hydrogen only shares a single (one) valence electron with carbon with carbon to form methane because of the
hybridization.
On the other hand, oxygen is able to share two (2) valence electrons with carbon to form carbon dioxide.
