You can put this solution on YOUR website! you have to substitute
T=a+(n-1)d if a=16 n=11 and d=6 then T=16+(11-1)6=16+60=76
T=a+(n-1)d if a=20 n=6 and d=-2 then T=20+(6-1)2=20+10=30
You can put this solution on YOUR website! T=a+(n-1)d
find t when a=16 n=11 and d=6
t = 16 + (11-1)*6
t = 16 + 10*6
t = 16 + 60
t = 76
-------------------
find t when a=20 n=6 and d=-2
t = 20 + (6-1)*2
t = 20 + 5*2
t = 20 + 10
t = 30
