1. The problem statement, all variables and given/known data Just a quick question I was looking to have cross checked… Q. Find un, the nth term of sequence -5, 0, 5, 10,… 2. Relevant equations un = a + (n-1)d 3. The attempt at a solution -5 + (n-1)5 -5 + 5n - 5 5n-10 The answer in the book, however, indicates that un = 5n. Am I wrong, or are they? Thanks.
