Xn = a +(n-1)d
96 = a + 13 d
173 = a + 24 d
---------------
-77 = -11 d
d = 7
then a = 96 - 13*7 = 5
so
X19 = 5 + 18*7 = 131 etc

LOL, yes :) good
173=a+24d
96=a+13d
77=11d
d=7
96=a+13×7
96=a+91
a=5
19th term = a+18d
5+18×7
=131
96=a+13d
77=11d
d=7
96=a+13×7
96=a+91
a=5
19th term = a+18d
5+18×7
=131
The14th term of an ap is 96 while the 25th term is 173 find the (a)the19th term (b)sum of 13th and 5th term (c)product of

Nothing
The forth term
Tn=a+(n-1)d
93=a+(14-1)d
96=a+13d---eqn(i)
173=a+(25-1)d
173=a+24d---eqn(ii)
a+13d=96
a+24d=173
