Best Answer

You need an equation for the nth term of the sequence, or some other means of identifying the sequence.

In general, they will be a+n, a+2n, a+3n and a+4n

although some go for a, a+n, a+2n and a+3n.

An excellent example of an arithmetic sequence would be: 1, 5, 9, 13, 17, in which the numbers are going up by four, thus having a common difference of four. This fulfills the requirements of an arithmetic sequence - it must have a common difference between all numbers.

Each number is four more than the previous number.

Question is not very clear about the context of word 'sequence' here. If I am to select 4 numbers out of four and arrange them in order then there are 4!*8C4 = 1680 different sequences possible. If the word sequence refers to some arithmetic sequence or geometric sequence, then counting is going to change for sure.

The first four terms are 3 9 27 81 and 729 is the 6th term.
