Trouble with print led program

Its suppose to princh each time the led blinks in the serial plotter/command box like 1 2 3 4 5 but it only shows 10 the total blinks

int ledPin = 11;
int blinkTime = 700;
int timesBlinked = 0;
 

void setup()
{
  pinMode(11, OUTPUT);
  blinkyBlinky(10, blinkTime); // 10 is number of blinks, blinkTime is the milliseconds in each state from above: int blinkTime = 500;
  Serial.begin(9600);
  Serial.print(timesBlinked, DEC);
  timesBlinked++; 
  
  Serial.setTimeout(500);
  
}

void loop()
{
 
  
  
}

void blinkyBlinky(int repeats, int time){
  
  for (int i = 0; i < repeats; i++)
  {
    digitalWrite(ledPin, HIGH);
    delay(500);
    digitalWrite(ledPin, LOW);
    delay(500);
    Serial.println(timesBlinked, DEC);
    timesBlinked++; 
  }
}

for command has to be used

You called

blinkyBlinky(10, blinkTime);

before

Serial.begin(9600);

You can't write with

Serial.println(timesBlinked, DEC);

before

Serial.begin(9600);

was called.

Swap the lines in setup:

void setup()
{
  pinMode(11, OUTPUT);
  Serial.begin(9600);
  blinkyBlinky(10, blinkTime); // 10 is number of blinks, blinkTime is the milliseconds in each state from above: int blinkTime = 500;
  Serial.print(timesBlinked, DEC);
  timesBlinked++; 
  
  Serial.setTimeout(500);
  
}
