Describing a discrete time LTI system by difference equation and impulse response

Consider a system where the output is a discounted summation of all previous inputs, which can be described by one of the following two input-output relationships;
- $y[n]=a y[n-1]+x[n]$
- $y[n]=sum_k=0^inftya^k x[n-k]$
It seems the first equation requires an initial condition to be evaluated, whereas the second equation does not. Do those two equations describe the same system? If so why does it require an initial condition additionally?
