Homework Help: Math Formula--General Term

Posted by Anonymous on Tuesday, September 13, 2011 at 10:36pm.

Consider the sequence 12, 5, -2, -9

Determine the formula for the general term of the sequence:

tn = a + (n-1)d
tn = 12 + (n-1)-7
tn = 12-7n + 7
tn = -7n + 19

I got -7n +19 as the answer, but at the back of the book, it says.. tn = 19-7n. I have no idea how the numbers got mixed up :\
