Find the first four terms of the sequence whose general term is given by:(a)5n+(1÷2)n_2,(b)2n+1÷3n+2

Answer 1

5n+(1÷2)n_2 ??? , makes no sense

b) 2n+1÷3n+2
Did you mean term(n) = (2n+1)÷(3n+2) , I will assume you did

term(1) = (2+1)/(3+2) = 3/5
term(2) = (4+1)/(6+2) = 5/8
etc

Answer 2

10,7,4,1,-2
