Ans:
Program to compute the average of every third integer between 1 and 200. Here are assuming 1 and 200 inclusive:

#include <stdio.h>
#include <conio.h>

void main(){
    float average;
    int i, sum=0, n=0;
    for(i=1; i<=200; i+=3){
        sum = sum + i;
        n++;
    }
    average = (float) sum / n;
    printf("\nAverage = %f", average);
    getch();
}
