Consider the recurrent sequence Xe = 1, x = 2, & n = (23n2 + Xn-1), n > 2 You will find below a MATLAB
Consider the recurrent sequence Xe = 1, x = 2, & n = (23n2 + Xn-1), n > 2 You will find below a MATLAB function that is written to find the nth term of this sequence. However, this m-file named RecSeq includes some mistakes to be detected. function [xn) = RecSeq(n) x(0)=1; x(1)=2; for i=2:n x(i)=(1/4)(x(i-2) +x (i-1)); end xn=x (n); 1. Mistakes exist in: a. Lines 1, 2 and 3 b. Lines 3 and 4 c. Lines 1, 2, 3, and 4 d. None of the above 2. Line 7 should be replaced by: a. There are no mistakes in line 7 b. This line is useless, we need to delete it c. xi = x(n) d. xn = x(n+1) 3. Line 1 should be replaced by: a. function [xn] = ReqSeq(n) b. function [xn] = Reqseq c. function [xn] = ReSeq d. The are no mistakes in line 1 4. Line 3 should be replaced by: a. for i = 0:n b. for i = 3: n+1 c. for i =i:n d. There are no mistakes in line 3 5. The value of X10: a. 0.0649 b. 0.043 c. 0.0268 d. 0.0173
