What should come in place of the question mark (?) in the given series?

201, 200, 197, 192, 185, ?​​

Given: 201, 200, 197, 192, 185, ?​​

Logic: Numbers are decreasing odd number from 1.

201 - 1 = 200

200 - 3 = 197

197 - 5 = 192

192 - 7 = 185

185 - 9 = 176

So, the missing term is 176.

Thus, correct option is (a).
