Instructions and help about Sequence No

in this video we're going to talk about how to find the next term in a series of numbers so let's say if we have the numbers 2 5 8 11 and 14 what is the next number in the sequence now what we need to do is we need to look for a pattern what pattern do you see in each of these numbers notice that each number has a common difference of three to go from two to five you need to add three likewise to go from five to eight you need to add three 5 plus 3 is 8 and 8 plus 3 is 11 whenever you have a sequence that differs by a common number this is an elliptic sequence if you can add or subtract by the same number you have an Arabic sequence so 14 plus 3 will give us the next number 17 17 plus 3 will give us the next number 20 so anytime you have a sequence that differs by repeated addition or subtraction it's an arithmetic sequence now let's work on another example let's say if we have these numbers 5 9 13 17 what's the next number in the sequence find the next three numbers actually feel fre
