How to change position of Adapter in Android

In my application I want change set new value to position of recyclerview adapter.
With java language I can it with below code: 

@Override
public void onBindViewHolder(MonthFragmentAdapter.ViewHolder holder, int position) {
    position += 6 - (position % 7) * 2;
}

But in kotlin I can't use below code and show me val error for position. 

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    position += 6 - position % 7 * 2
}

Show me Val cannot be reassigned! I know I can't set new value for val, but how can I change my code for fix it?

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    var newPosition = position
    newPosition += 6 - newPosition % 7 * 2
}

Use a new variable to change the value.

It is Kotlin feature, you can't change the function parameter.
