Here is one formula that you can use:

black = (blue / 3) + 1

And, solving for blue in terms of black,

blue = 3(black - 1)

Also, the pattern starts with 5 beads, and

increases by multiples of 4 beads. That's always

going to give you an odd number, so 48 beads

is impossible.

2 black => 3 blue

3 black => 6 blue

4 black => 9 blue...(not 8 as you say)

5 black => 12 blue

blue = 3(black) - 3

or, blue = 3(black - 1)

so, with 10 black beads we have:

blue = 3(10 - 1) => 27...(not 25 as you state)

When there are 66 blue beads we have:

66 = 3(black - 1)

so, black - 1 = 22

Hence, black = 23

For the total beads we have:

5, 9, 13, 17,...

All odd numbers, so will 48 appear in this sequence??
