a + 3d = 96
a + 24d = 173
subtract them
21d = 77
d = 11/3
a + 3(11/3) = 96
a = 85
so term(6) = a + 5d = 85 + 55/3 = 310/3
in the same way, find term(3) and term(10)
then do the calculation asked for
The 4th term of an A.P is 96 while the 25th term is 173 find sum of 3rd term and 6th term and product of 6th and 10th term
