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.

If the 20th term in a sequence is 50 what is the 21st term?
Oh, dude, you just add one to the term number to get the next term. So, if the 20th term is 50, the 21st term would be the 20th term plus the common difference of the sequence. It's like basic math, man.
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
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.
