tn = a + (n - 1)d find t24 ?
tn = a + (n - 1)d For given sequence a = 0
rth term from the end = (n - r + a)th from the begining a = 4 d = 9 - 4 = 5 n = 254
tn = a + (n - 1)d a = 1 d = \\({1 \\over 4}\\)
a+26d
tn = a + (n - 1)d a = 1, d = 3 Put tn as 157.
tn = a + (n - 1)d a = \\( \\sqrt{3} \\)
3a+18d
2x2 = 2450
nth term = a + (n - 1)d
