Q. If f(1)=4 and f(n+1)=f(n)2+3 then find the value of f(4).Answer:
Given initial condition and formula: We are given the initial condition and the recursive formula for the function f:f(1)=4f(n+1)=f(n)2+3We need to find the value of f(4). We will start by finding f(2) using the given recursive formula. Substitute n=1 into the recursive formula to find f(2).f(2)=f(1)2+3f(2)=42+3f(2)=16+3f(2)=19
Find f(2): Now that we have f(2), we will use it to find f(3). Substitute n=2 into the recursive formula to find f(3). f(3)=f(2)2+3f(3)=192+3f(3)=361+3f(3)=364
Find f(3): Finally, we will use f(3) to find f(4). Substitute n=3 into the recursive formula to find f(4). f(4)=f(3)2+3f(4)=3642+3f(4)=132496+3f(4)=132499
