Question

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

recursive:An-1+1

Answer 1

In the recursive, if you meant

A_n = A_n-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.
