23-2n
this guy has a great way of explaining it, so look at his...
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
It is increasing by 4 and the nth term is 4n+1
19
after -9 it is -15 then -21, -27 and the ninth is -36
To find the nth term of this sequence, we first need to determine the pattern or rule governing the sequence. By examining the differences between consecutive terms, we can see that the sequence is increasing by 9, 15, 21, 27, and so on. This indicates that the nth term is given by the formula n^2 + 1.
It is: 27-2n
The nth term is 25-4n and so the next term will be 5
2n +29
It is 4n+5 and so the next term will be 25
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
nth term = 5 +8n
It is increasing by 4 and the nth term is 4n+1
Clearly here the nth term isn't n25.
You can see that all the numbers go up by 7. This means that the first part of the nth term rule for this sequence is 7n. Now, you have to find out how to get from 7 to 3, 14 to 10, 21 to 17 ... this is because we are going up in the 7 times table. To get from the seventh times table to the sequence, you take away four. So the answer is : 7n-4
To find the nth term of a sequence, we need to identify the pattern between the numbers. Looking at the differences between consecutive terms, we see that the differences are increasing by 9, 15, 21, and so on. This indicates that the sequence is following a pattern of adding consecutive odd numbers (1, 3, 5, 7, ...). Therefore, the nth term of this sequence can be expressed as n^2 + 7.
The given sequence (7, 14, 21, 28, 35,....) is an arithmetic sequence where each term increases by 7. The nth term of the given sequence is 7n
It is 5n-4 and so the next term will be 21
