The Uncommon Ratio

When we first started sequences and bases, I thought that it was going to be easy. It turns out I was wrong. For a long period of time I couldn’t answer most of the word problems in the unit. Eventually, I found out that it was because I was using the “common ratio” right out of the problem. Now, I know that you should write out at least the first two terms in the sequence and divide them to find the common ratio. There still are some small things that I have to remember, like adding the initial values when needed. I almost always forget to do this. I also, have to review some problems like the bouncing ball question. I’m pretty sure that there will be a question similar to this on the test.
