The question can be restated as follows:
Given: ONE * THREE * FIVE = 225
X is determined by:
NINE * SEVEN + TWELVE = X
Y is determined by:
225 + X = Y
? is the next number in the following sequence:
10,18,32,56,93,146,?
Solve for Z satisfying:
? + Y = Z

Is it 93 for sure? If it is 90, I have a pattern to solve.

Can you tell us how you (or google ) come up with this answer?

Apart from the sequence the rest is fairly straight forward...
Hint: Think about ONE * THREE * FIVE = 225. What three numbers could multiply to make 225 such that their relationship to one another is 1, 3, and 5?
However, I just can't figure out that sequence, as the answer would require 223 to be the next term.
Clearly there is no determinable polynomial relationship due to no constant difference being found. But working with the idea that one of the terms is wrong would indicate that 93 should be 94. Yet this would lead to the next term being 228.
Interestingly there is the start of a (coincidental?) relationship:
10 * 18/10 = 18
18 * 16/9 = 32
32 * 14/8 = 56
56 * 12/7 = 96 (which is where it goes wrong).
And this would lead to the next two terms being 160 and 256.
Any ideas?

If you assume the first term is 11 and not 10, you get a degree 3 polynomial and the next terms are 218 and 312.
Or by changing 2 terms, you get
(21),18,(31),56,93,146,223
About the sequence 10,18,32,56,96,160, interestingly, if you compute the differences, you get 8,14,24,40,64
and you have the relation again:
8 * 14/8 = 14
14 * 12/7 = 24
24 * 10/6 = 40
40 * 8/5 = 64
Not much help, I guess.

Another aside, Sloane recognizes this sequence; not sure if that'll lead to any clues about the original though.

Great discussions here. I agree that this is a challenging and interesting question. According to the website, the question is at IQ level of 170.
Have A Great Day!

Since when does 1*3*5=225. I claim the answer to be no solution, for the question provides false information.

Not all claims are valid. For example, I claim that you demonstrate some signs of intelligence, but clearly your post provides false information.
The problem doesn't say 1*3*5 = 225. To make the problem solvable the creator has cleverly mapped the value of the word to the value of each factor. In fact, the beauty of his system is the internal consistency: ONE * THREE * FIVE = FIFTEEN.
Now go figure it out, but if you want to make yourself useful around here try helping us out by working out that sequence.

I aggree that this has little to do with intelligence. But it is fun. Someone might be able to figure the sequence soon.

ONE*THREE*FIVE=225
is not the same as
1*3*5=225
for a myriad of reasons, not least of which
"one" does not equal "1".
The first subject is a collection of shapes called letters that arrange themselves into a word that we can give a meaning.
The other is a glyph/character that we typically assign a meaning.
Yes, they can be used to mean the same thing, but not always. "One"
What if, for example, F=I=V=E=R=1; T=N=3; 0=H=5
(not that I think this is the answerl- this one's beyond me at the moment)

If that bothers you then you won't like the fact that in this system, THREE + FOUR = FIVE. 
Come on, temporary. Look at the clues:
ONE * THREE * FIVE = 225
ONE * THREE * FIVE = FIFTEEN

It's not a big jump to go from here to the value of X. Try to think outside of the box... or should I say, the "square"...
It is the sequence that seems to be the head-scratcher.

"ONE" IS not 1. it is the variables "O", "N", and "E" multiplied together. Same thing w/ the rest. if it is uppercase, it is a variable. this is where it gets hard.

Not necessarily. In this case, ONE = 12, THREE = 32, FIVE = 52, and ONE * THREE * FIVE = 12 * 32 * 52 = 225, and this pattern allows you to find X -- the words themselves act as variables here.

It has been quiet here for a while. As a hint, 10,18,32,56,93,146,? is a nested recursive function. You can find that ? = 224.

I worked on this for a while but could not get that 146 to fit in anywhere. If anyone is interested there is a full explanation here (warning this is a complete spoiler):
