find the number of terms using
an= a+(n-1)×d

find (an) using the formula again
an= a+(n-1)×d

oh
there are total 60 terms in the given ap series . therefore the 7 term from last is 54 th term
here 54 is n, then substitute in n term formula
an = a + (n-1)d
common difference (d)= 3
a = 7
yeah I know those
ohk carry on
thanks
welcome.
