🌘 What Is 1 3 5 7 9
11 , 3 3 , 5 5 , 7 7. This is an arithmetic sequence since there is a common difference between each term. In this case, adding 2 2 to the previous term in the sequence gives the next term. In other words, an = a1 +d(n−1) a n = a 1 + d ( n - 1). Arithmetic Sequence: d = 2 d = 2.Explanation This is the sequence of the odd positive integers where the nth term (an) is: an = (2n −1) for n ∈ N Answer link T_n = 2n -1 This is clearly an arithmetic sequence because the terms differ by 2 each time. To find the nth term rule we need: a value for the first term , a and a value for the common difference d . Eachnumber in the series, and any combination of those numbers is a subset of 1,3,5,7,9. To be more clear, 1 is a subset, so are 3,5,7 or 9. 1&3 are also a subset, so are 5&7 and 7&9. all of the numbers less any one of the numbers is also a subset. so 1,3,5,& & are a subset. as is 3,5,7&9. get it?
