Sequence in Layers Excersize

The youngest rock layer would be 3 because it is an intrusion so the other layers would have to have already been there. The next youngest layer would be 1 because the second intrusion doesn't go through it so it must have already been there and number 1 is at the top. Number 6 would be the next youngest because number 2 doesn't go through it and its the next layer below number 1. I think the next youngest layer would be layer number 2 because it's an intrusion that goes through the remaining layers of rock so it has to be younger. The second oldest layer of rock would be number 5 because it is above 4 if the vertical line were the fault is was even. The oldest rock layer would be number 4 because it would be at the bottom if the fault didn't happen and 2 also went through 4 before it went through 5.
