Answer 1

object EvenSumApp {
  def main(args: Array[String]): Unit = {
    val N = 5
    var sum_even = 0

    // The sum of the first N even numbers is N * (N + 1)
    sum_even = N * (N + 1)

    println(s"The sum of the first $N even numbers is: $sum_even")

  }
}

// 2 + 4 + 6 + 8 + 10 = 30


/*
run:

The sum of the first 5 even numbers is: 30
