What is the nth term in the sequence 21 17 13 9?
Oh honey, looks like we're counting down by 4 each time. So, if we keep that pattern going, the next number would be 5. So, the nth term in this sequence is 21 - 4n, where n is the position of the term in the sequence.
What is the nth term for 3 10 17 24 31?
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
What is the formula for the nth term for the sequence 12-21-30-39-48?
> 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
Find the missing numbers 13 10 17 15 21?
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

What is the nth term of the sequence 13 17 21 25 29?
The given sequence is an arithmetic sequence where each term increases by 4. The first term (a) is 13, and the common difference (d) is 4. The nth term can be found using the formula: ( a_n = a + (n-1)d ). Therefore, the nth term is ( a_n = 13 + (n-1) \cdot 4 = 4n + 9 ).
Is 5 9 13 17 21 25 29 33 37 41 what is the pattern?
It is increasing by 4 and the nth term is 4n+1
What is nth term for sequence 25 23 21 19 17?
It is: 27-2n
What is the nth term for 7 9 13 21 37?
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

What is the Nth term of 25 24 23 22?
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
What is the nth term for 4 13 28 49 76?
To find the nth term of the sequence 4, 13, 28, 49, 76, we first identify the differences between consecutive terms: 9, 15, 21, 27. The second differences, which are constant at 6 (6, 6, 6), suggest that the sequence is quadratic. The nth term can be expressed as ( an^2 + bn + c ). By solving the equations based on the first few terms, we find the nth term is ( n^2 + 3n ).

What is the nth term of 6 15 28 45 66?
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!
Why is the nth term n2 5 if the sequence is 6 9 14 21 30?
Clearly here the nth term isn't n25.
What is the nth term of 8 17 32 53 80?
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.
