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.

What Find the 90th term of the arithmetic sequence 16,21,26?
The 90th term of the arithmetic sequence is 461
How do you find the next 50nth term in a sequence?
you must find the pattern of the sequence in order to find the next 50 terms using that pattern and the first part of the sequence given
How do you work out the nth term of a sequence?
Find the formula of it.
How do you find the 20th term in triangular sequence?
20th term = 20*(20+1)/2
If the 20th term in a sequence is 50 what is the 21st term?
46
What is the 20th term for the sequence 3 6 9 12?
It is 60.
How do you find the nth sequence term?
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 be2n+1you always use n for the nth sequence term
What is formed by multuiplying a term in a sequence by fixed number to find the next term?
what term is formed by multiplying a term in a sequence by a fixed number to find the next term
How do you find the 100th term of the sequence?
a + 99d where 'a' is the first term of the sequence and 'd' is the common difference.
What Find the 90th term of the arithmetic sequence 16,21,26?
The 90th term of the arithmetic sequence is 461
What is the 20th Fibonacci number in the sequence?
The 20th Fibonacci number in the sequence is 6,765.
What is the 20th term of 16 13 10 7 4 1 etc?
The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41
What are the first four terms of a sequence and what term number is -32 when the nth term is 8 -2n?
If the nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number
How do you find the next 50nth term in a sequence?
you must find the pattern of the sequence in order to find the next 50 terms using that pattern and the first part of the sequence given
How do you find the nth term of a nonlinear sequence?
If the sequence is non-linear, you need to establish how it is defined.
