Explanation / Answer

% Matlab program to find the sum of the list of numbers under various
% conditions
% subset of given list , replace the entire list
x = [29,67,71,33,46,79,91,44,12,39,69,11,84,56,84,23,96,97,45,53,97,91,64,73,50,18,19,37,10,30,18,30,87,79,54,34,59,45,69,61,74];

second_sum=0;
second_list=0;
ns = 1;
%A. loop to find the sum of every other number beginning with the first number
for i=1:2:length(x)
second_sum = second_sum + x(i);
second_list(ns) = x(i); % create a list of every second number of x
ns = ns+1;
end
% B. loop to find the sum of every second number in the previous
% list(second_list) starting with the second number
next_sec_sum =0;
for i=2:2:length(second_list)
next_sec_sum = next_sec_sum + second_list(i);
end
% C. loop to find the sum of all values less than 49
sum_less_49 =0;
for i=1:length(x)
if(x(i) < 49)
sum_less_49 = sum_less_49 + x(i);
end
end
% D. loop to find the sum of (x(i)+i)^2 for all i=9 to 155
sq_x = 0;
for i=9:155
if(i < length(x))
sq_x = sq_x + ((x(i)+i)^2);
end
end
% print the result
fprintf(' Sum of every other element in x starting from first number : %d',second_sum);
fprintf(' Sum of every other element in previous list starting from second number : %d',next_sec_sum);
fprintf(' Sum of element in x less than 49 : %d',sum_less_49);
fprintf(' Sum of (x(i)+i)^2 for i=9 to 155 : %d',sq_x);

  
% end of program
