What should come in place of the question mark (?) in the given series?
51, 87, 121, 153, 183, 211, ?
Given:
Series: 51, 87, 121, 153, 183, 211, ?
Logic: the difference of these terms decreasing by 2.
87 – 51 = 36
121 – 87 = 34
153 – 121 = 32
183 – 153 = 30
211 – 183 = 28
Clearly, the difference is decreasing by 2 each time.
So, next difference = 26
→ 211 + 26 = 237
Final Answer: 237
