Can't find location of implicit cast

I'm trying to find the total of two given number arrays for my assignment, but I keep receiving the error:

Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)

int[] firstarray= new int[4] { 4, 20, 60, 150 };
double[] secondarray= new double[4] { 5, 40.5, 65.4, 145.98 };

firstarray[0] = 20;
secondarray[1] = 5;

int totalarrays = firstarray[0] + secondarray[1];
Console.WriteLine("Total of the two arrays " + totalarrays);

Answer Source
int totalarays = firstarray[0] + secondarray[1];

should be

double totalarays = firstarray[0] + secondarray[1];

An int + a double ends up in a double. If it didn't you would lose the precision of the double in the result - there is no implicit way to do that.

If you need to convert the double to an int there are many different techniques depending on your requirements.
