What are the differences between arithmetic and geometric sequences? An arithmetic sequence has a constant difference between each term. For example: 2,4,6,8,10,12,… We can see …

The fact that we needed to take 2 turns to find the constant difference means we are dealing with a quadratic sequence. (3) Furthermore, because the difference is +4, we are dealing with a 2n …

The first three terms of an arithmetic series are p, 5p – 8, and 3p + 8 respectively. (a) Show that p=4 (b) Find the value of the 50th term in the series.

To do this, the first thing we do is calculate the difference between each term.7 - 3 =411 - 7 = 415 - 11 = 4The difference each time is 4. Therefore, the equation could be 4n. Let's try it out with …
