Inverting the A.P,
a=184
d=-3
So,
a₈=a+7d
=184+7(-3)
=184-21

∴8th term from the last is 163

a - 7
d - 3
l - 184
8 ^ th term from the last term = ( l-( n - 1 ) d )
( 184 - ( 8 - 1 ) 3 )
184 × 21
= 3864
d - 3
l - 184
8 ^ th term from the last term = ( l-( n - 1 ) d )
( 184 - ( 8 - 1 ) 3 )
184 × 21
= 3864
