What is the nth term for 11 9 7 5?

Answer 1

Oh, dude, it's like a pattern party! So, to find the nth term for this sequence, you first need to figure out the pattern. Looks like each number is decreasing by 2. So, the nth term would be 13 - 2n. Easy peasy, right?

Answer 2

The given sequence is decreasing by 2 each time, so the pattern is -2. To find the nth term, we can use the formula for the nth term of an arithmetic sequence: (a_n = a_1 + (n-1)d), where (a_n) is the nth term, (a_1) is the first term, (n) is the term number, and (d) is the common difference. In this case, the first term (a_1 = 11), the common difference (d = -2), and we want to find the nth term. So, the nth term formula becomes (a_n = 11 + (n-1)(-2) = 13 - 2n).
