For this, have logic unit applied on screen 1 and use following snippet

if (input == 1) {
$.ChangeFlow(3)
// // or 
// $.ChangeFlow(screen + 2)
}

How to show different previous Screen

When changing forward flow, form may require change in previous screen flow. For this in screens there is setting for previous screen when allow going back to previous screen is checked. User can use drop down and select which screen to show when back button is pressed.
