First, you must find the difference between the numbers, for example if the numbers were 3, 5, 7, 9, 11 then it would be 2. All you have to do is find out the difference between 2 and the first number, which happens to be 3. So 3-2 equals 1.
so the equation would be
2n+1
you always use n for the nth sequence term
Start out by finding the expression that describes the sequence. This is often in the form an + b.
Example: Find the 20th term in the following sequence: 3 7 11 ...
It appears that 4 is being added to the previous term to make the next term. However, instead of starting at 4, the sequence started at 3. The expression is:
4n - 1
Plug in the 20 to replace n, to give: 4*20 - 1= 79
Answer: The 20th term in the sequence is 79.
Find the formula of it.
The given sequence is an arithmetic sequence with a common difference of 6. To find the nth term of this sequence, we can use the following formula: nth term = first term + (n - 1) x common difference where n is the position of the term we want to find. In this sequence, the first term is 1 and the common difference is 6. Substituting these values into the formula, we get: nth term = 1 + (n - 1) x 6 nth term = 1 + 6n - 6 nth term = 6n - 5 Therefore, the nth term of the sequence 1, 7, 13, 19 is given by the formula 6n - 5.
i dont get it
If the sequence is non-linear, you need to establish how it is defined.
123456789 * * * * * The nth term is 3n
The nth term is Un = a + (n-1)*d where a = U1 is the first term, and d is the common difference.
6n-5 is the nth term of this sequence
the first 4 terms of the sequence which has the nth term is a sequence of numbers that that goe together eg. 8,12,16,20,24 the nth term would be 4n+4
A single number, such as -3052 cannot define a sequence and, without a sequence you cannot have an nth term.
The nth term is (36 - 4n)
Three or more terms of a sequence are needed in order to find its nth term.
The nth term of the sequence is 2n + 1.
