In an attempt to find a power series solution to an ordinary differential equation, our professor illustrated the concept with an example. As a try-at-home exercise, the following homogeneous equation was given:

y''-5y'+6y=0

The above differs from his example critically - a_k+2 is in terms of a_k+1as well asa_k which yields a2,a3,a4... in terms of a1&a0.

My calculatios are here:

The next step of separing a0 & a1 terms is proving to be erroneous.

Would aprpeciate some assistance.

Best,
