Well, it would depend what the sequence was...? If the sequence was 2,4,6,8,10,12,14,16,18,20, then the 9th term would be 18!
It is 3.562963 approx. a = 0.009009... recurring. d = 0.033957 approx
The sequence, -7, -21, 63 could be generated by Un = 49n2 - 161n + 105 so when n = 9 the term would be 2625.
It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b
That depends what the pattern of the sequence is.
The 9th term of the Fibonacci Sequence is 34Fibonacci Sequence up to the 15th term:1123581321345589144233377610

In order to answer the question is is necessary to know what the explicit formula was. But, since you have not bothered to provide that information, the answer is .
The 9th number in the Fibonacci Sequence is 34, and the 10th number in the Fibonacci sequence is 89.
It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b

An infinite sequence.
It is called a term.Each number in a sequence is called a term.
a + 99d where 'a' is the first term of the sequence and 'd' is the common difference.
The 90th term of the arithmetic sequence is 461
