Logically the next note is B, C, D... so on and so forth but the note only reach G and then it will turn to A again.
When you play the violin, make sure that the bow is parallel with the bridge.
Try pulling a note, ensure that the bow stays parallel do not let it slip.
Keep doing that because before you can play anything you need to get full control of the bow know where is the heavy where is the light part. This will allow you to play notes steadily.
