Here are the first five terms of a sequence. 12 19 26 33 40 Find an expression for the nth term of this sequence.
12 - 5(n-1)
Find the formula of it.
If the sequence is non-linear, you need to establish how it is defined.
The nth term is: 4n
i dont get it
If you mean 3, 6, 9, 12 then the nth term is 3n
Three or more terms of a sequence are needed in order to find its nth term.
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.
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.
