Answer 1

// Loop to print the N terms

// Loop to print the N terms // of the series and find their sum

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) {

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) {

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi;

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi; cout << multi << " ";

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi; cout << multi << " "; multi = multi * x;

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi; cout << multi << " "; multi = multi * x; }

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi; cout << multi << " "; multi = multi * x; }

// Loop to print the N terms // of the series and find their sum for (i = 1; i < n; i++) { total = total + multi; cout << multi << " "; multi = multi * x; } cout << "\n";
