Hey there!
“6 + r = 8”
• FIRST: FIRST THE EQUATION
r + 6 = 8
• SECOND: SUBTRACT by 6 on BOTH SIDES
r + 6 – 6 = 8 – 6
CANCEL out; 6 – 6 because that gives you 0
KEEP: 8 – 6 because that helps solve for your r-value
• THIRD: SOLVE FOR YOUR EQUATION
8 – 6 = r
• FOURTH: ANSWER THE QUESTION
8 – 6 = 2
FIFTH: ANSWER
r = 2 ☑️
Good luck on your assignment and enjoy your day!

Answer:
Sure, the common difference is -3, but like you have to multiple it and stuff, so it goes like this: -2,6,-18,54,-162,486,-1458,4374,-13122,39366,-118,098,354294.
So then, add all of the 12 terms I stated, and that will equal to 265,720
Therefore, the sum of the first 12 terms of that geometric sequence is 265,720.
Step-by-step explanation:
Answer:
A. 4
Step-by-step explanation:
First, we can try the first option. 2/4 is equivalent to 6/12 when you multiply the fraction by 3 to get a common denominator. Since 6/12 is larger than 4/12, and the question has 1 answer, 4 is the only value that satisfices the statement and is the answer.
Answer:
482
Step-by-step explanation:
We can see that the numbers shown resemble an arithmetic sequence because they have a common difference. The formula for the nth term of an arithmetic sequence is:
Where 
is the first term, 
is the nth term, and 
is the common difference. To find the 61st term, all we need is the first term and the common difference. By looking at what given, we can say the first term is 2. Now, to find the common difference, we find the difference of a term from the term before it. In this case we can do 
, which is 
, or the common difference. Since we have everything we need, it can be plugged into the equation:
So, the 61st term is 482.
+ 22) -12
