1. Algebra 1 Number Sequences

2. Introduction What are the next two terms and what is the pattern? Two must be ADDED to the previous TERM Three must be ADDED to the previous TERM +2 +3

3. Introduction What are the next two terms and what is the pattern? -5 -7 Five must be SUBTRACTED from the previous TERM Seven must be SUBTRACTED from the previous TERM

4. Exercises 1 What are the next two terms? What is the pattern? Remember to answer every question like this +2 +5 +9 +8 -4 -7 -6 a b c d e f

6. Exercises 3

7. Number Chains How many different ways can a number sequence start with number one and finish with number ten? Must the same number be added every time? +1 +3 +4+5

8. Number Chains Think of different ways of starting a number chain with: +4 ×5 +4+5+6+7 Adding 4 to the previous TERM REGULAR difference Difference increases by ONE more every time Multiplying the previous TERM by 5.
