Number series is a progression or an ordered list of numbers governed by a pattern or rule. Numbers in a sequence are called terms. A sequence that continues indefinitely without terminating is referred to as infinite sequence, whereas a sequence with an end is known as finite sequence. Questions related to Number Series series questions can be solved by using Square or Cube like exponents. In this method, we will square or cube and using addition / subtraction to get the second term. Using the same method, get the third term and so on. On the basis of the result, we will find the next number in the series.
Number | Square | Cube |
1 | 1 | 1 |
2 | 4 | 8 |
3 | 9 | 27 |
4 | 16 | 64 |
5 | 25 | 125 |
6 | 36 | 216 |
