Question 1127085
<br>
Given the form for Tn, it is clear that you have a typo in the given sequence.  The second term is 1/10, not 1/0; the 5th term is 10/25, not 0/25.<br>
It would be polite (and beneficial to you) for you to look at what you have written in your post before submitting it.<br>
Then there is not much to show....<br>
The numerators are -2, 1, 4, 7, 10,...; they follow the pattern 3n-5.  The denominators are 5, 10, 15, 20, 25,...; they follow the pattern 5n.<br>
So the fractions follow the pattern (3n-5)/(5n).
