Worksheet 3: 6 Arithmetic and Geometric Progressions
If we know the rst term in an arithmetic progression, and the dierence between terms, then we can workout the nth term, i.e. we can workout what any term will be. The formula which tells us what the nth term in an arithmetic progression is u n =a+ (n1) d where ais the rst term.
