first we will find the difference between the first two fractions
1/8-1/16=
here the common dinominator is 16 so we will get the following out of the subtraction
1/8-1/16=1/16
D=1/16
to get the next three, we will just add the difference to the previous fraction to get the next fraction.
so our pattern will be 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16
