Here's a puzzle! On Mars, 1 is 2, 2 is 4, 3 is 9 and 4 is 16. What is 15 on Mars?
And said the answer is 225, heh, just because. He's wrong and he wins the bozo of the day award. There are several right answers, math being what it is, there are lots of was to match a few numbers. These days you can put these numbers into mathematica and it will spit out several polynomial answers. However, 225 isn't any of the ones that work.
Here's the simplest one I found: the nth square plus the nth prime.
The first integer square of integers is 0, the first prime is 2. One is not prime, it has only one divisor, a prime has two divisors. So f(1) = 2
The second square is 1, the second prime is 3. So f(2) = 4
The third square is 4, the third prime is 5. So f(3) =9
The fourth square is 9, the fourth prime is 7. So f(4) = 16.
The table below runs this out to 15.

By the way, his name is Don Paulo according to Twitter, and he is peddling an educational game. What is he teaching? That being a vicious jerk is right, because, well, he had an answer in mind, and it has to be right, no matter what the numbers say.
It's not a light hearted exercise in logic, it is just another corporate shill trying to take your money.
Buy something that is actually educational.
