Boston har vuxit snabbt de senaste tio åren.

English Translation

Boston has grown rapidly in the last ten years.

I would have put DEN here, rather than DE. Could you expand on why it should be DE, please?

It’s in the plural, so it has to be DE. Contrast that to “den senaste tioårsperioden”, or “det senaste årtiondet”.
