l= last term = 184
d= common difference= 10-7=3
therefore, 7th term from the end = 184+(7-1)(-3)
[ because nth term from the end = l+(n-1)(-d)
= 184+6(-3)
= 184-18
= 166
d= common difference= 10-7=3
therefore, 7th term from the end = 184+(7-1)(-3)
[ because nth term from the end = l+(n-1)(-d)
= 184+6(-3)
= 184-18
= 166

l=184
a=7
d=-3
a7 =l+(n-1)d
=184+(7-1)-3
=184+6(-3)
=184-18
=166
