your answer
now given to us :-
last term =184
common difference = 3
first term =7
first take out number of terms
l=a+(n-1)×d
184=7+(n-1)×3
184-7/3=n-1
177/3=59+1=60=n
now most important thing is that whenever asked to take out nth term form ap use formula
(n-rth term +1)
so
(60-7+1)=60-6=54
hope helps

the answer is not correct
what's the answer?
its answer is 166
but to take out the terms from last we use the formula n-r+1
just wait i send you a whole answer
184...........13,10,7. d=7-10=-3. a=184 n= 7 a7. = a+6d. a7=184+6(-3). a7=184-18=166. hence 166 is 7term of an AP
but 184 is last term
