I saw this question only once, as the first of 4 problems on the final exam for my very first EE introductory course. The course had covered an infinite ladder of resistors, but at the time it seemed like quite a leap to apply that knowledge to this problem.

This was the question I hated in my EE degree. The thought exercise was a favourite of the profs.
