Answer 1

Mustakim Rahman ,

in this case just posting your code may not be sufficient. it is extremely helpful to also create and share a suitable task description.

Answer 2

When <i> = 0
rangeArray[ 0 ] = 2 + 0

When <i> = 1
rangeArray[ 1 ] = 2 + 1

When <i> = 2
rangeArray[ 2 ] = 2 + 2

When <i> = 3
rangeArray[ 3 ] = 2 + 3

And when <i> = 4
rangeArray[ 4 ] = 2 + 4

And so on, until <i> equals 10, where loop ceased repetition.

Simple a is already 2

So rangeArray[4] = 2 + 4 = 6;
