You need to determine the equation for the general term. That will depend on whether the sequence is additive, multiplicative, or something else. The generating equation will depend on the term's position and putting that equal to 20 will provide the answer.

Additive: 3, 5, 7 ,9 etc (each number is 2 more than the previous one).

Multiplicative: 2, 6, 18, 54, etc (each number is three times the previous one).

Fibonacci: 1, 1, 2, 3, 5, 8 etc (each term, after the first two, is the sum of the previous two).

There can be sequence generated by quadratic, cubic or any other functions so there is no simple way of answering this question.

How do you find the nth term of a sequence?

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.

What is the 20th term of the following sequence-6 -4 -2 0?

As can be seen, each succesive term is 2 greater than the last. We can write a rule to calculate the nth term. Here the rule equals 2n - 8. So the 20th term = (2 * 20) - 8 = 32.

How can you figure out the random number sequence?

Well, by definition a "random number sequence" is random; i.e. you cannot find out the next term.However if you're just trying to find the formula for a "number sequence" (not random):1) look at what you have to do to get from one number in the sequence to the next - example the initial difference between the numbers may give a sequence such as "+4, +6, +8, +10", this then gives a sequence of "+2, +2, +2 etc." - this does help to to find out the formula for the sequence.2) write down the "term numbers" (call this "t") above or below the sequance, (i.e. 1st term, 2nd term etc.) and see what you have to do to get from the term number to the sequence number. i.e "3t-1", "t squared minus 3" etc.
