Mathematical Riddles for Teens to Complete the Series


Mathematical Riddles for Teens to Complete the Series
Recently I was playing a game in Lumsoity called Fuse Clues. In this game one has to complete the number patterns. The way they have designed this game is that there are many houses in an apartment and in some of these houses electricity is not there which one need to restore by completing the mathematical series. The moment one completes the series correctly, connection gets completed in the game turning on the bulb and lights in the house.
These mathematical series are very much fun to solve and it helps to improve the logical reasoning by enhancing the ability to recognize patterns, draw conclusions and thus make correct decisions. I thought to creating a post in which one has to complete the mathematical series. One need to have knowledge of only basic mathematics operations to complete these series. Lets see many many of these series one can complete without looking that answers of these riddles. Difficulty of these math brain riddles is from medium to hard. So these can be used by high school students for testing their mathematical skills :). In each of these mathematical series one has to tell what are the next numbers on the series with logical conclusions.
Answers of these series are given at the end of this post. Please do post your answers in the comment section of this post.
