A7

Question: Find the 6th, 7th and 8th term of the sequence below.

1,  5,  9,  13,  17

 

Solution: A good first thing to check out with any sequence is the difference between each of the terms. In this case, the difference between each term is 4, so now we know the rule is

“add 4 to the previous term to get the next term”

Therefore, the 6th, 7th, and 8th terms respectively are:

21,\,25,\,29
