i didnt make it up sorry i found it on the web
oOo:

My own creations: the first is rather easy, the second depends on your level
of base 2, 8 or 16 knowledge and finally, the third will have you tearing your
hair out. Have fun...

This is an analogy.
y = 3(x - 5) : L :: y = (x - 1)(x + 1) : ?

The second is related to binary/hex or octal
10, 171, 3004, 52429, 908766, x

Find the value of x

This one should give you a headache:
1621 2432 6448 x

Find the value of x and explain your reasoning.

Another cutie...

1.500, 1.667, 1.400, 1.571, ?

wow confusing. as for that second one u posted, not the green but the decimals. is it 1.300? im just guessing...

OWCH!

Answer = 61167

Reason

Decimal converted to binary then to hex

10 > 1010
171 > 10101011
3004 > 10111011100
52429 > 1100110011001101
908766 > 1101110111011110

upon converting to binary - convert to hex and get these results.
000A
00AB
0BBC
CCCD
DDDE
as you can see it makes a pattern
EEEF
This converts to
1110111011101111
converts to decimal:
61167

if i have time later i'll see if i can attempt no 3

CLOSE but no dice... (hint: no reason for binary conversion)

I dont know how to convert directly from decimal to hex. Will keep trying to solve it.
