Question

In MATLAB

Write a script to determine the number of terms required for the sum of the series (5k? – 2k) not to exceed 100,000 using the while loop. Display the number of terms and the calculated sum using fprint () command as follow: The number of terms is 38 and its sum is 93613

Answer 1

clc;
clear;
close all;
sum = 0;
max = 100000;
k = 0;
while (sum < max)
k = k+1;
sum = sum + (5*k^2 - 2*k);
if sum > max
n = k-1;
sum = sum - (5*k^2 - 2*k);
break
end
end
fprintf('The number of terms is %g and its sum is %g \n',n,sum);
