The nth term is 7n-5 and so the 6th term will be 37
Just plug in 30 for n in 3n-1. The answer is 89.
Say if you had the pattern 15 20 25 30 35 40 45 50 To find the nth term you have to see what the gap between the numbers is. In our case this is 5. Then you have to find out what the difference between the gap and the first number. In this sequence it is 10. So your answer would be..... 5n+10 That's how you find the nth term.
Clearly here the nth term isn't n25.
t(n) = 3n2 + n = n(3n + 1)
Looks like 57: 12+9=21, +9=30, +9=39, +9=48, +9=57.

The given sequence is 22, 14, 6, -2, -10. To find the nth term, we observe that the sequence decreases by 8, 8, 8, and so on. This indicates a linear relationship with a common difference of -8. The formula for the nth term can be expressed as ( a_n = 22 - 8(n - 1) ), which simplifies to ( a_n = 30 - 8n ).
Oh, dude, you're hitting me with the math questions, huh? So, the formula for finding the nth term of an arithmetic sequence is a + (n-1)d, where a is the first term and d is the common difference. In this sequence, the common difference is 8 (because each term increases by 8), and the first term is 14. So, the formula for the nth term would be 14 + 8(n-1). You're welcome.

There are infinitely many possible answers. But the simplest is Un = 33 - 3n for n = 1, 2, 3, ...
6n+10
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.
The nth term is 7n-5 and so the 6th term will be 37
I made a program that made the next 25is sequences after 16. It starts at #3 because 30 is #3 Here it is: 30 48 70 96 126 160 198 240 286 336 390 448 510 576 646 720 798 880 966 1056 1150 1248 1350 1456 1566 1680
