Find out the wrong number in the series 196, 169, 144, 121, 100, 80, 64
Answer: D
The series is the squares counting down from 14.
\[ 14^{2},\; 13^{2},\; 12^{2},\; 11^{2},\; 10^{2},\; 9^{2},\; 8^{2} = 196,\; 169,\; 144,\; 121,\; 100,\; 81,\; 64 \]
The sixth term should be \( 9^{2} = 81 \), not 80.
So 80 is the wrong number - off by one from a perfect square.
