This week we had our Arithmetic and Geometric sequences and series test. One thing that I was still unsure about before the test was finding “r” when you are given and Once I asked questions to my classmates to get a better understanding I understood how to do it.

Line thig that I have really enjoyed so far is how we can rely on the people in our table group to help us when we need it. I was really struggling with this question and when I asked for help with my table group everyone was happy to help. With the he’ll hey gave me I now understand how to do questions like these and I also know that I can count on them for any other questions I may have.

This past week we have learned many new things about geometric and arithmetic sequences and series. One thing that I have struggled with throughout the week has finding a term when you don’t have the difference.

Steps: The first thing you need to do is find the difference (d)

1. First I wrote out my formula

2. I then substituted the numbers in where they should be. I got “x” by subtracting the subscripts under “t” (8-3=5)

3. I then solved, trying to isolate the variable (d). I had to move 4 to the other side so I had to subtract it from one side which means I had to do the same to the other side so I did 34-4=30

4. Once I had 30 = 5d, I just had to divide 30 by 5 and 5d by 5 to isolate “d”

5. Once I did this I got 6=d which means I have my difference

Once I have my difference I can use it to solve and find any other term in the sequence
