The nth term of a geometric series is tn and the common ratio is r. where r>0 Given that t1 = 1. (a) Write down an expression in terms of r and n for tn. Given also that tn+t(n+1)=t(n+2). (b) Show that r = 1+√5/2. (c) Find the exact value of t4 giving your answer in the form of f+g√h, where f, g and h are integers.
