Question

a) Write amethod that calculates the result of the following formul: X2+ (x+ K2+ (x +2K)7 + (x + 3K ... + (x + nk)? ‘The header of the method is as follows public static double sum(double x. double k. int n) b) Write a main method in which you ask the user to enter the value of x, and then call the sun method to print the result of the above sum with k = 2.5 and n = 10. Sample run 1: Enter the value of x: 4.5 The result of the sum is: 3866.5 Sample run 2: Enter the value of x: -1.2 The result of the sum is: 2092.09

a) Write a method that calculates the result of the following formula:
x? + (x + k)? + (x + 2k)? + (x + 3k)?+ .
+ (x + nk)?
...
The header of the method is as follows
public static double sum(double x, double k, int n)
b) Write a main method in which you ask the user to enter the value of x, and then call
the sum method to print the result of the above sum with k = 2.5 and n = 10.
Sample run 1:
Enter the value of x:
4.5
The result of the sum is: 3866.5
Sample run 2:
Enter the value of x: -1.2
The result of the sum is: 2092.09
