Question 118888
Let's look at the fourth clue. It says "My number is less than the 3rd square number and larger than the 2nd square number". The 3rd square is 9 and the 2nd square is 4. So our number is between 4 and 9. Now looking at the first clue, we know that the number is even. So our number could be 6 or 8 (it cannot be 4). 


If we factor 8, we get


8:2*2*2


which shows that the factorization of 8 has a string of three numbers. So this eliminates 8 and leaves us with 6




So our number is 6.
