int textY = 10;
int textX = 10;
int numLines;
int yDist = 15;
String[] lines;

void setup() {
size(500, 400);
lines = loadStrings("README.txt");
numLines = height/yDist;
}

void draw() {
background(0);
int counter =0;
for (int i = 0; i < numLines; i=i+2 ) {
text(lines[i], textX, (yDist*counter++), width, 20);
}
}

Use BufferedReader and a simple test to load or ignore each line

<reading loop>
...
thirdLine++
if( thirdline % 3 )....load the line
...
<end reading loop>
