Last term ( l ) = 184
n = 7
Common difference ( d ) = 10 - 7 = 3
To find the term from end of the A.P
formula is :-
• al = l - ( n - 1 )d
a7 = 184 - 6 × 3
a7 = 184 - 18
a7 = 166
So,
the 7th term of an A.P is 166
n = 7
Common difference ( d ) = 10 - 7 = 3
To find the term from end of the A.P
formula is :-
• al = l - ( n - 1 )d

a=7
d=10-7=3
l=184
So,
a7 from the end
=l-(n-1)d
=184-6d
=184-6x3
=184-18
=166
d=10-7=3
l=184
So,
a7 from the end
=l-(n-1)d
=184-6d
=184-6x3
=184-18
=166
