So, you have made it to the third in our Easy series of Eleven Plus maths quizzes on Number Sequences – well done for making it so far! In this quiz, just like the others, we shall ask you to predict which number comes next. That might seem impossible – no one can predict the future. But once you spot the rule governing the series, the answers become obvious.
It’s all about spotting the pattern. Here’ an example:
2, 6, 18, X, …
Which number comes next? This is where trial and error comes in. The numbers are increasing so we’re either adding or multiplying. 6 is 4 more than 2, but 18 is 12 more than 6, so addition seems unlikely. Okay then, 2 x 3 = 6, and 6 x 3 = 18. We’ve found the rule. So, the next number will be 18 x 3 = 54.
See how simple it is? Now you are ready to take the quiz. Good luck!
