If any of you have some other valid answer , please feel free to share it. I will post my answer later. It looks like you have a sequence where it's x, x^2, (x+3), (x+3)^2. So following this logic, the next two are 8, 64. Quote Link to comment Share on other sites More sharing options...

Was that supposed to be 26x26, or am I not understanding correctly? Quote Link to comment Share on other sites More sharing options...
