solvefor f,f(f(n))+f(n+1)=n+2

solve for

f, f (f (n)) + f (n + 1) = n + 2

f = \frac{n + 2}{f ( n ) + n + 1}; f (n) + n + 1 \neq = 0

Solution steps

f (f (n)) + f (n + 1) = n + 2

ff (n) + f (n + 1) = n + 2

Expand

f (n + 1) : n f + f

ff (n) + n f + f = n + 2

Factor

ff (n) + n f + f : f (f (n) + n + 1)

f (f (n) + n + 1) = n + 2

Divide both sides by

f (n) + n + 1; f (n) + n + 1 \neq = 0

f = \frac{n + 2}{f ( n ) + n + 1}; f (n) + n + 1 \neq = 0

f = 2 lo g_{10} (10)
