1. Why isn’t (1, 1) a solution of the system of linear inequalities y > -x and y > x +1?

2. Topic #13: Patterns When finding the missing number, the next number, or the n th number of a sequence, it is necessary to figure out the pattern or rule of the sequence. You need to determine if the numbers are increasing or decreasing and by how much.

3. Which of the following best describes the pattern 11, 14, 17,...? A) n + 6, n + 9, n + 12 B) n – 15, n – 12, n - 10 C) 2n, 3n, 4n D) n/2, n/3, n/4

4. Another type of problem asks you to find the formula to find the n th term of the sequence. Which expression can be used to find the n th term of the sequence 18, 31, 44, 57, … A) 13n - 5 B) 13n + 5 C) 13n 2 - 5 D) 13n 2 + 5

5. In the next problem we need to find a specific term. Find the 7 th term of the sequence 19, 13, 7,…

6. If the pattern continues, what expression could represent the number of blocks in the n th term in the sequence?
