Suppose, you have been given the task of repeating a number and increment that number and repeat it. For example -

1,1,1,1,2,2,2,2,3,3,3,3.....(Here, we are repeating it 4 times and incrementing and repeating 4 times again and so on)

Then you can use following formula


Suppose, you want to start the number with 5 not 1, then you can use below formula -


Hence, general structure of the formula is


X - Number of times a particular number is repeated
Y - Starting Numbers

Hence, if you want to start with number 7 and you want to repeat it 5 times, then following formula should be used
