Q. If f(1)=1 and f(n)=f(n−1)2+3 then find the value of f(3).Answer:
Find f(2): Given the recursive function f(n)=f(n−1)2+3 and the initial condition f(1)=1, we need to find f(3). We will start by finding f(2). f(2)=f(2−1)2+3 f(2)=f(1)2+3 Since we know f(1)=1, we substitute this value into the equation. f(2)=(1)2+3 f(2)=1+3 f(n)=f(n−1)2+30
Find f(3): Now that we have f(2), we can find f(3) using the same recursive formula.f(3)=f(3−1)2+3f(3)=f(2)2+3We already found that f(2)=4, so we substitute this value into the equation.f(3)=(4)2+3f(3)=16+3f(3)=19
