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
