The nth term is 25-4n and so the next term will be 5
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
> since the value rises by nine at each step and the first term is 12 the formula for > the nth term is: 12+(n-1)*9 Which simplifies to Sn = 9n + 3
n'th term: n^2 + 5
13 10 17 15 21 13 - 10 = -3 10 - 17 = +7 17 - 15 = -2 15 - 21 = +6 The negative numbers alternate with the positive numbers The negative numbers are augmented by +1 each step The positive numbers are diminished by -1 each sterp So the next step from 21 is a negative and should be -2 increased by +1 to -1 giving a new value of 20 Then the next step is a positive and should be +6 decreased by -1 to +5 giving 25 13 - 10 = -3 10 - 17 = +7 17 - 15 = -2 15 - 21 = +6 21 - 20 = -1 20 - 25 = +5
The nth term is 25-4n and so the next term will be 5
nth term = 5 +8n
It is increasing by 4 and the nth term is 4n+1
It is: 27-2n
The problem is finding the next term 7 9 13 21 37 69 133 261......... nth the first number aka the N1 = 7, N2 = 9, N3= 13,....... N7= 133,........Nth The first number 7 +2 = 9, which is the second number NOTE: 21=2 the second number 9 + 4 = 13 NOTE: 22=4 the third 13 + 8 = 21 NOTE: 23=8 the fourth 21 +16 = 37 NOTE: 24=16 So, the pattern is Nm+2m= the next number in the pattern Nth = Nth-1+2th-1 By: Rodney T. Anderson
23-2nthis guy has a great way of explaining it, so look at his...What_is_the_nth_term_for_3_7_11_15_19
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
Clearly here the nth term isn't n25.

Oh, what a lovely sequence you have there! To find the pattern, let's look at the differences between the numbers: 9, 13, 17, 21. Do you see how the differences are increasing by 4 each time? That means the nth term is found by adding the square of n to the previous term. Happy math-ing, my friend!
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
