It's not at all interesting to know how much they've sold NOW. What's interesting is how much and how fast they sold albums back then.

And as you can see 5150 sold around the same amounts for the first 6 months as 1984.

Van Halen's debut most likely started to sell more after Jump was released and 1984 started to sell again after 5150 was released. That's usually how consumer patterns work.
