To rewrite these equations in standard form you need to understand that standard form looks something like this Ax+By=C, now obviously there will be variations like </span>Ax-By=C or -Ax+By=C, etc..., but for these expressions, they would look like this:
<span>
1. -8y + 0x = 372. 14x </span>
+ 4y<span>
= -183. x + </span>
y =
<span>
4. 13x + 0y = -25

The general term of an arithmetic sequence is
an = a1 +(n-1)d
Your sequence has first term a1 = 11 and common difference d = 4. Then the general term is
an = 11 + (n-1)*4
The simplest form of the general term is
an = 7 + 4n
