When solving systems of ODEs with more than two equations I am unsure if I am properly expanding on the above ideas.

For example I am trying to find a system of three first order equations:

da/dx = 2bc + 3a

db/dx = 4ac +11b

dc/dx = 5ab + c

Using and expanding on the equations above would I be correct in the following:

K0 = 2bc + 3a

L0 = 4ac +11b

M0 = 5ab + c

k1 = 2*(b+(L0)/2)*(c+(M0)/2) + 3*(a+(K0)/2)

L1 = 4*(a+(K0)/2)*(c+(M0)/2) + 11*(b+(L0)/2)

M1 = 5*(a+(K0)/2)*(b+(L0)/2) + (c+(M0)/2)

And so on for K2,L2,M2 etc?

Hopefully that's fairly readable.

Is this the correct approach to take or am I making a glaring error somewhere?
