1500, 1581, 1664, 1749, 1833, 1925, 2016
[Bank of Baroda (PO), 2008]
Explanation
According to the question
⇒ 1400+(10)²=1500
⇒ 1500+(9)²=1581
⇒ 1600+(8)²=1664
⇒ 1700+(7)²=1749
⇒ 1800+(6)²=1833(1836)
⇒ 1900+(5)²=1925
⇒ 2000+(4)²=2016
∴ Wrong number= 1833
∴ Right number = 1800+(6)2=1836.
Hence, Option C is correct.
