Mrs. Quimary presented these number patterns to his Math class.

1, 3, 7, 15, 31, 63

​

What do you think is the rule/pattern used to find the 2nd term? 3rd ? 4th? 5th? 6th?

1 x 2 + 1 = 3 15 x 2 + 1 = 31

3 x 2 + 1 = 7 31 x 2 + 1 = 63

7 x 2 + 1 = 15

Patterns : ( x 2 + 1 ) or ( +2, +4, +8, +16, +32 )

​

1, 3 , 6, 10, 15, 21, 28, 36, 45

Find the missing terms in the following situations below:

The numbers inside the pentagon are multiplied by consecutive odd numbers 3, 5, 7. Starting with 3 x 3 = 9, then 9 x 5 = 45, then 45 x 7 = 315, so the missing number in the last pentagon is 2 835 ( 315 x 9 = 2 835 ).

The series of numbers inside the hexagon uses even numbers as factors. So, the missing number inside the last hexagon is 768( 96 x 8 =768 ).

Study the rule/pattern. Supply the missing terms.
