Is this correct? Write an explicit and recursive formula: -5,-4,-3,-2,-1... explicit: -5N+1
recursive:An-1+1

In the recursive, if you meant
An = An-1 + 1 , you should have included, n > 1, A1 = -5

In the recursive notation, the initial value(s) has to be included or else you can't start the thing off.
