1. "My left arm has been achy <b>for the past</b> few days"<br/><br/>2. "Record events <b>for the past</b> 7 days"<br/><br/>3. "I've been away <b>the past</b> few weeks"<br/><br/>Is the <b>for</b> not included in the 3rd phrase before it's preceded by an adverb instead of a noun or adjective or is it a different reason?<br/><br/>Thank you
