Three of them.

Three numbers can be arranged in 27 different sequences if repetition is allowed, and in 6 different sequences if it's not.
There are infinitely many possible number sequences, and infinitely many numbers which can appear in those sequences. Any and every number can appear in a number sequence.
There are 900 three digit numbers. (99 - 1000) (# of possible numbers in the first position = 9) (# of possible numbers in the second position = 10) (# of possible numbers in the third position = 10) 9 *10 *10 = 900
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.
You can use sequences ending in every number from 3 to 25 so 23 times.
There are many possible answers: -1, +1 and -147 is one possible triplet.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.

There are 20 different sequences.
There are infinitely many numbers between them. Also there are infinitely many sequences that wil have two numbers between 1000 and 1.
There are many possible answers. One is 5, 7 and 7499
There are infinitly many possible answers. One possible triple is -10, +10 and -1.8
