Please, Vlad, write that in mathematical symbols.  You might get faster results that way.

Right, I have no idea if it's this:

$$-7 \frac{ 3 }{ 5 }, -8,-12\frac{ 2 }{ 5 },-13$$

thank you for posting that illustration.  SO much clearer!

the formula for the nth term of an arith sequence is     L=A+(n-1)D,

...where A is the first ter, n is the nyumber of terms, D is the difference (gap) between terms, and L is the last term.
