3,7 change in four

7, 15 change in eigth

15, 31 change in 16

31, x = change in 32

x, y = change in 64

second one you add half of the value

ie 1/2 + (1/2)(1/2) = 1/2 + 1/4 = 3/4

It takes 3 + 4 to equal 7.

It takes 7 + 8 to equal 15.

all you’re doing is multiplying the number that adds to the next number by 2.

for example

2 times 2 equals 4, and 4 + 3 = 7

4 times 2 equal 8 and 8 + 7 = 15

the rule is: x*2+1

0,1/2,3/4,7/8,15/16, 31/32, 63/64

the rule is: multiply the denominator times two and make the numerator one less than the denominator

1,3,7,15,31,63,127

on the first number you add 2, then you add 4, then you add 8, then 16, then 32, then 64

2.1/2,3/4,7/8,15/16,31/32,63/64

basically you just multiply both numbers by 2 then to the numenator you just add 1

All you do is times 2 and add one. So it would be 62 and 124

2.) The bottom numbers just keep times by 2.

The top numbers have the same pattern as number one.

Good luck!

2. 31/32, 63/64 i can’t explain this one though
