Heya friend ..
a' First term =17 .
l' last term =-40
n= no. of term =10
d'(common difference)=t2-t1=14-(-17)=3
for finding the tn term from the last term formula is
tn=l-(n-1)d
t10=-40-(10-1)3
=>-40-27
=>-67 is t10 ...
Hope it helps you.

How ??
But we can apply a+(n-1)d also where a =-40 .Answer is exactly same.
Try and check the answer. Aren't they same??
So we have to find tenthterm from the last term itself.
