数组循环如何对其自身进行三倍计时

Question

I am new to java, and I am trying to make the below array to make it times itself three times. The output is currently the same. How do I make it so it makes the output: let's say input i=1 and output will be {3,6,12} so it times the number before that three times.

double [] conversion = new double [3];
for(int i=0;i<conversion.length;i++){
    conversion[i]=3*bytes;

Answer 1

double [] conversion = new double [3];
for(int i=0;i<conversion.length;i++){
    conversion[i]=3*i;

But where comes bytes form, why do you use it

Answer 2

You'd want to set the first value in the array to 3x your input, and then just loop through the values after that.

int inputNumber = 1;
int[] conversion = new int[3];
conversion[0] = inputNumber * 3;
for(int i = 1; i < conversion.length; i++) {
    conversion[i] = conversion[i-1] * 3;
}
