call different variables with the same prefix changing only suffix

I have 20 variables (it may be 20 different mutableList items, or it may be a 20 buttons or any other objects), for example: 

var ex1 
var ex2 
var ex3 
...
var ex20

And i need to make a for loop, which will look like this:

for (i in 0 until 20) {
//here i want to do something with variable that i have declared earlier
i+1
}

so, how can i go throught all the variables?

Create an array var[] ex and insert all the twenty var elements to that array. Iterate the array inside the for loop to access the 20 var elements

It's not really possible, you should really take a look into using arrays for this kind of behavior. 

val array = arrayOf(5, 32, 555, 921)

//To get numbers in array
for(num in array) {
    //Do something
}

//To change numbers in array
for(i in 0 until array.size) {
    array[i] = 2
}
