For instance, let's say I give you the following two questions,

1. find the next number in the sequence:
1, 1, 2, 3, 5, 8, 13, ?
Someone who learned about the fibonacci sequence could easily find it. Doesn't even need to think for more than 5 seconds. And there are IQ tests that use the fibonacci sequence. For instance, pic related.

Then, let's say I gave you a second question:
2. find the next number in the sequence:
1, 1, 11, 111, 5, 5111, 10111, ?
Would you be able to solve it? It's probably harder but possible, but there is no way you can solve it if you don't know a specific numbering system.

And just for fun, let's give you another example.
3. Find the next word in the sequence:
B,B,BA,BB,BAB,BAAA,BBAB,?

All of those should be solvable and are examples of questions on IQ tests. I just rewrote them in a different system, which some people should be able to solve if they learned it, and those who haven't shouldn't be able to. And this is exactly what IQ tests ask of the person. Use your previous knowledge to solve those ones. Whether it's adding, subtracting, rotating, translating, shifting and so on. Those are all patterns that come up, and if you're familiar with them, should be able to easily detect them. If you're not familiar, you won't. Saying otherwise shoes you cannot put yourself in the place of someone who's never opened a math textbook in his life. You didn't learn how to add on your own and chances are, if you were born in the middle of nowhere, and never exposed to it, would never figure out any of it, unless it's been taught to you or you've experienced something gave you the need to develop such knowledge. 2/2

What is the answer here? This is a question from the entry-level civil servant exam. The rest of the IQ test-style questions make more sense. The source is https://twitter.com/jeeebediah/status/1270917940888719360..
