A = -4
d = -1 - ( -4 )
= -1 + 4
= 3
a + ( n - 1 ) d = 101
-4 + ( n - 1 ) 3 = 101
( n - 1 ) 3 = 101 + 4
( n - 1 ) 3 = 105
( n - 1 ) = 105 / 3
(n - 1 ) = 35
n = 35 + 1 = 36
d = -1 - ( -4 )
= -1 + 4
= 3
a + ( n - 1 ) d = 101
-4 + ( n - 1 ) 3 = 101
( n - 1 ) 3 = 101 + 4
( n - 1 ) 3 = 105
( n - 1 ) = 105 / 3
(n - 1 ) = 35
n = 35 + 1 = 36

apply formula an=a+(n-1)d
101= -4+(n-1)(-5)
and then solve for n.
