Well, honey, if the nth term is 3n-1, then all you gotta do is plug in n=30 and do the math. So, the 30th term would be 3(30)-1, which equals 89. There you have it, sweet cheeks, the 30th term of that sequence is 89.
3n+7
What is the 2nd term of 3n-2?
1+3n
Just plug in 30 for n in 3n-1. The answer is 89.

(3n)(3n-1) = 3n * 3n - 3n * 1 Now, perform the multiplication: (3n * 3n) = 9n^2 (3n * 1) = 3n So, (3n)(3n-1) simplifies to: 9n^2 - 3n
3n+7
3n(n+1] + 5 is the nth term
The Series has the formula 3n + 1/2(n - 1)(n - 2) = 3n + 1/2(n2 - 3n + 2) which simplifies to, 1/2(n2 +3n + 2)

What is the 2nd term of 3n-2?
The sequence given is 3n + 1, where n represents the term number. To find the 15th term, substitute n with 15: 15th term = 3(15) + 1 = 45 + 1 = 46. Therefore, the 15th term in the sequence is 46.
1+3n
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
