You cannot have mixed speeds on both ends of your connections.  In your case, the 3850 with 10G SFP will not link up with the 2960x with a 1G SFP.  Check out this URL for the 3850 Network Module information:

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/hardware/installation/guide/b_c3850_hig/b_c3850_hig_chapter_011.html#reference_9C2D0B956A434DD49CEFC6AB2E1150BF

Scroll down to Network Module Port Configurations and it will list what modules support what speeds.  It looks like the 10G modules will support 1G speeds, you would just need to buy a 1G SFP for the 3850.
