Series completion is such a topic out of which at least one question is always asked in SSC CGL exams including both Tier-1 and 2. In this, you are given a series of numbers, strings or miscellaneous with a missing number or string. You are required to find it out. The numbers or strings in the series follow a particular logic or pattern. You have to identify it and apply to figure out the next number or string. It is the test of your cognitive and logical manipulation skills.
In this article, we have covered up approximately 20 questions with their answers based on this topic. Go through these and check your knowledge before appearing in SSC exams.
