Numerical Test 7 (Number Series)
So far we have seen examples of numerical tests that have tended to focus on mathematical ability, with a small amount of problem solving involved. Now we turn our attention to some more difficult numerical ability tests that expressly address problem solving – how well you can identify which mathematical calculations you need to perform in order to reach the correct answer.
It is less important in this type of test to be able to carry out straightforward mathematical calculations – the emphasis is on how you get to that point. Note again that as in Test 6 the actual mathematical calculations involved are sometimes quite simple once you know what they are.
Type of test: Speed/Power
Typical length: 15–25 questions
Typical time allowed:
