7. Introduction into Chapter 2: We use inductive reasoning to find patterns. Once we have discovered the pattern, then we can continue the pattern to find the next terms in a sequence.

8. Find the next number in the pattern. 12, 8, 4, 0, -4, ___, ___ -4 **TIPS: Find the patterns between numbers and see if this pattern is continuous. Check if a constant is multiplied, divided, added or subtracted. If you don’t initially find a pattern, then check patterns in second differences. Continue subtracting 4 to find the missing values. -8 -12

9. Find the next number in the pattern. 20, 10, 5, 2.5, 1.25,___,___ Continue dividing by 2 to find the missing values. 0.625 0.3125

10. Find the next number in the pattern. 8, 24, 72, 216, 648, ___, ___ Continue multiplying by 3 to find the missing values. 1944 5832

11. Find the next number in the pattern. 6.2, 7.9, 9.6, 11.3, 13,___,___ Continue adding by 1.7 to find the missing values. 14.7 16.4

12. Find the next number in the pattern. 1, -2, 3, -4, 5, ___, ___ next number & alternating signs Continue on the next consecutive number and alternating signs to find the missing values. next number & alternating signs next number & alternating signs next number & alternating signs next number & alternating signs -6 next number & alternating signs 7
