AS WE HAVE TO FIND THE 17TH TERM FROM LAST SO WE ARE REVERSING THE AP
. the new AP by reversing =
216,211,.....1
a= 216
and the new d will be -5. Now we have to find 17th term
an = a+ (n-1)d
an = 216+ (17-1)(-5)
an = 216-80
an = 136
. the new AP by reversing =
216,211,.....1
a= 216
and the new d will be -5. Now we have to find 17th term
