Best ResponseYou've already chosen the best response.1let's try 4th onedw:1443788458435:dw \[\huge\rm a_n=a_{n1}+2(n+1)\] substitute n for 4 \[\large\rm a_\color{Red}{4}=a_{\color{ReD}{4}1}+2(\color{reD}{4}+1)\] 41 = 3 so a_{41} =a_3 now substitute a_3 for 10 bec `after 3 days , there are 10 cells` is same as a_3 =10 \[a_4=10+2(5) ~~~~~~~~~~~~~~~~~~~~~~a_4=20\]but we should get 16 so D is wrong now try other 3
