Google math is fun arithmetic sequence
a , a+d, a+ 2d , ..... a + (n-1) d
if n = 14
a + 13 d = 96
if n = 25
a + 24 d = 173
so
a - a + (13-24)d = 96-173
-11 d = - 77
d = 7 whew, whole number, the rest is easy :)
The 14th term of cm AP is 96 while the 25th term is 173 from. (a)19th term (b)sum of 13th and 56th term (c)product of 6th and 13th term
