Well, to word it more easily, adding a negative is just subtracting.
Here are some examples to help:

10 - 5 = 5. right? so...
10 + (-5) = 5.

An arithmetic sequence with a third term of 8 and a constant difference of 5.
larisa [96]
An arithmetic sequence (a_n) is as follows:

a_1\\a_2=a_1+d\\a_3= a_1+2d\\a_4=a_1+3d,... where a_1 is the first term and d is the constant difference, 

thus, we see that the n'th term of an arithmetic sequence is a_n=a_1+(n-1)d


in our particular case d=5, the third term is 8, so we have:

a_3=8=a_1+2\cdot5\\\\8=a_1+10\\\\a_1=-2


and the general term is a_n=-2+5(n-1),


Answer: first term is -2, n'th term is -2+5(n-1)
