plant is growing weird sets of leaves

my plant has been growing sets of like 4, 6, and 8 leaves but it also grows normal sets of leaves too is there any reason a plant does this?, and should i worry? it looks fine except for the weird sets of leaves.

 

Don't worry, its not like you can do anything about it. Its prolly just a genetic mutation. I wouldn't let it get seeds though.
