If \(7 \rightarrow 50\), \(8 \rightarrow 65\), then \(9 \rightarrow ?\)
82
Look for a rule that turns each number into its image. Test "square the number, then add 1".
For 7: \(7^2 + 1 = 49 + 1 = 50\), which matches.
For 8: \(8^2 + 1 = 64 + 1 = 65\), which matches.
Apply the same rule to 9: \(9^2 + 1 = 81 + 1 = 82\).
Hence, 9 maps to 82.
