How can I turn this code into a simple loop using **‘for’** command?  
The first circle is the smallest circle, each circle, fill subtracts 30 and size grows by 10. The x and y stay the same.

```auto
void setup(){
  size(500, 500);
}

void draw(){
  background (0);
  noStroke();
  fill(100);
  ellipse(250,250,60,60);
  fill(130);
  ellipse(250,250,50,50);
  fill(160);
  ellipse(250,250,40,40);
  fill(190);
  ellipse(250,250,30,30);
  fill(220);
  ellipse(250,250,20,20);
  fill(250);
  ellipse(250,250,10,10);
}

```

try

```auto
for (int i=5;i>=0;i--) { fill( 250 - i*30); ellipse(250,250,10+10*i,10+10*i); }

```
