Recognizing patterns in number sequences is all about finding out what comes next in a row of numbers. For instance, do you know which number should follow this sequence 20, 15, 10, 5? Well, the numbers are decreasing. or getting less, each time. Each number is 5 less than the one before it. To find the next number in the sequence we need to take 5 away from 5 which will give us the answer 0.
