We are learning to identify the rule for a pattern of numbers

Multiplication practice:

56 ➗ 8 = 7        72 ➗ 9 = 8     44 ➗ 11 =4

45 ➗ 9 = 5             64 ➗ 8 = 8 56 ➗ 7 =8

35 ➗ 5 =  7 144 ➗ 12 = 12         27 ➗ 3 =9

82 = 64                 92 = 81                    72 =     49      

62 =     36

Finding the rule: What are the next numbers in the pattern? What is the rule for the pattern? 1 2 3 4 5 6 7 4 7 10 13 16 19 24 The rule is: n x 3 + 1 The 20th number in the pattern is 61

1 2 3 4 5 6 7 4 9 14 19 24 29 34

The rule is: n x 5 - 1

The 100th number in the pattern is 499

1 2 3 4 5 6 7 1 8 27 64 125 216 343

The rule is: n x n x n

The 10th number in the pattern is= 100

1 2 3 4 5 6 7 8 15 22 29 36 43 50

The rule is: n x 7 + 1

The 100th number in the pattern is 701
