hello, I was trying to find the nth term of iii and when I did my calculations, it didn't match up with the book.
nth term = 1+ (n-1) (1.5)
= 1+1.5n - 1.5
= 1.5n - 0.5 (What I got as answer)
instead the book's answer was nth term = 1/2(3n-1) which was different from my answer. Why is my answer different?
