Answer:
the ap is 3, 5, 7, 9, 11
Step-by-step explanation:
n = 50, last term = 101, d = 2
50th term = a + 49d
101 = a + 49(2)
101 = a + 98
a = 101 - 98
a = 3
general form of an ap : a, a+d, a+2d
= 3, 3+2, 3+2(2)
= 3, 5, 3+4
= 3, 5, 7

Step-by-step explanation:
n=50
an=101
d=2
solve then,
an=a+(n-1)d
101=a+49×2
101=a+98
101-98=a
a=101-98=3
