![]() When practicing, avoid using a calculatorĮven if you are allowed to use a calculator on your test, you’ll be doing yourself a favor by answering practice questions without a calculator. Our brains are better at processing smaller numbers and can recognize sequences easier. This is often the case when numbers towards the end of the sequence are smaller than at the beginning. Certain people are often stronger suited at multiplication or addition sequences, but cannot answer division or subtraction sequences as quickly. Sometimes a simple change of perspective can make a complicated number sequence question appear obvious. While taking the test, try to eliminate obvious pattern sequences – for example, if the numbers are changing exponentially, you can rule out a simple addition or subtraction sequence and consider whether the sequence is a multiplication/division sequence, an alternating sequence with multiplication/division and addition/subtraction, or if it incorporates other patterns like a multiplication sequence with an irrelevant number. This is where experience plays a big factor, which can only be obtained by answering practice test questions and reviewing the answers. Identify the type of number sequenceĪs outlined above, there are a number of sequences that are common on standardized tests, and identifying the sequence in play is often the hardest part of number sequence questions. There are a few strategies that you can utilize when taking a number sequence test. This is a multiplication sequence of 2 with 15 being an irrelevant number in the sequence. Question: What number should be included in this sequence? 22, 2, 22, 4, 22, 8, 22Īnswer: 16. This is an addition sequence of 4 with 15 being an irrelevant number in the sequence. Question: What number comes next in the series? 8, 15, 12, 15, 16, 15Īnswer: 20. Sometimes numbers in a series are included in a sequence for no purpose at all. This is an alternating subtraction then multiplication sequence. Question: What number should be included in the gap in this number sequence? 32, 20, 40, 28, _, 44.Īnswer: 56. This is an alternating addition then division series. Question: What number comes next in the sequence? 249, 254, 127, 132Īnswer: 66. For example, the first number may be added by 5, then divided by 2, then added by 5, then divided by 2, and so on. Quite often a series will switch between adding, subtracting, multiplying or dividing by a given number. Each number is multiplied by 4 then divided by 2. ![]() Question: What number comes next? 2, 8, 4, 16, 8Īnswer: 32. Each number in the sequence is divided by 3. Question: What number comes next? 3, 9, 27, 81Īnswer: 243. Numbers may be divided or multiplied in a set or alternating series. ![]() Question: What number comes next? 48, 42, 36, 30.Īnswer: 24 – Each number in the sequence is reduced by 6 Division & Multiplication Series Each number in the sequence increases by 10 Question: What number comes next? 11, 21, 31, 41.Īnswer: 51. These are one of the simplest and easiest to identify in a number series, where numbers are added or subtracted in a set order. The following are some number sequence examples that commonly appear on aptitude tests, going from simplest to more complicated. You can keep these number patterns in the back of your head, which will make it easier to identify the number sequence and solve the problems faster. Luckily, many questions follow numerical patterns that you can identify with practice. Number sequence questions are featured on a wide range of aptitude tests such as the GCSE and Wonderlic.
