5. Numerical reasoning – mathematical pattern
At first sight, it’s a bunch of numbers ‘arranged’ in line. What do they have in common? Are they arranged in a way to follow a rule? The title says it all. It’s a pattern, a sequence. It’s not necessarily Fibonacci’s sequence – with all due respect to The Da Vinci Code fans – where every next number is the sum of the previous two numbers. In fact, that’s the catch – to recognize the pattern and to figure out the missing link (number) that will complete the sequence. So, you can divide, multiply, add, and subtract, just pick the right answer. Try to answer the question number 4 on our list of Mensa IQ test questions you need to answer to join Mensa.
