AP
-1 , -5/6 , -2/3 ................................, 10/3
common difference d = -5/6 - (-1) = 1/6
a = -1
nth term = a + (n-1)d
10/3 = -1 + (n-1)(1/6)
=> 20 = -6 + (n-1)
=> 26 = n -1
=> n = 27
6 , 3, 0 , -3 ..............., -36
a = 6
d = 3 -6 = -3
-36 = 6 + (n-1)(-3)
=> 12 = -2 + (n-1)
=> 14 = n-1
=> n = 15
