Question Discussion & Solution

The given series is following-

For the first term 

15 + 20 = 35 

35 + 20 = 55

55 + 20 = 75

75 + 20 = 95

For the middle term

F + 2 = H

H + 2 = J

J + 2 = L

L + 2 = N

For the third term

35 + 35 = 70

70 + 35 = 105

105 + 35 = 140

140 + 35 = 175

Hence, the correct answer is 95 N 175.
