Can anyone help me to find this font..?

First letter would be small, second one is bigger than first, third one is bigger than second, fourth one is just same as the second one and fifth one would be same as the first one… Plss help me to find out this font… (want described font)

That would be accomplished by the software that sets the font, not the font itself. For example, in InDesign, you can apply a series of nested character styles of varying type sizes and have them repeat small, medium, big, medium, small.
