### How to convert a symbolic recursive formula to a non-recursive one

I am new to Mathematica. I want to convert a recursive formula to a non-recursive one using symbolic math. Specifically, I have a recursive formula similar to this: $a_n = f_a(c_{n-1}, x_{n-1})$ \$...
### Is there an integral number k satisfying the equation a[n] = k^2?
I have a sequence a[n] with $$a(n+1)=4 a(n)-2 a(n-1),\quad a(0) = 1,\ a(1) = 28.$$ I use ...
