Select the number from among the given options that can replace the question mark (?) in the following series.

228, 209, 192, 179, 168, (?)

The series is: 228, 209, 192, 179, 168, (?)

Logic: The numbers decrease by consecutive prime numbers in descending order: –19, –17, –13, –11, –7.

Let's check the series: 

228 – 19 = 209

209 – 17 = 192

192 – 13 = 179

179 – 11 = 168

So, next difference = –7

Therefore, the missing term in the series should be 168 – 7 = 161. ​​​​

Thus, the correct option is: (d)
