Q. If f(1)=3 and f(n)=f(n−1)2+5 then find the value of f(4).Answer:
Given f(1): We are given f(1)=3. To find f(4), we need to find the values of f(2), f(3), and then f(4) using the recursive formula f(n)=f(n−1)2+5. First, let's find f(2). f(2)=f(1)2+5=32+5=9+5=14
Find f(2): Now, let's find f(3) using the value of f(2).f(3)=f(2)2+5=142+5=196+5=201
Find f(3): Finally, we find f(4) using the value of f(3).f(4)=f(3)2+5=2012+5=40401+5=40406
