.tg .tg-baqh{text-align:center;vertical-align:top}
.tg .tg-amwm{font-weight:bold;text-align:center;vertical-align:top}
| \(x\) | \(1\) | \(2\) | \(3\) | \(4\) | \(5\) | \(6\) | \(7\) |
|---|---|---|---|---|---|---|---|
| \(P(x)\) | \(k-1\) | \(3k\) | \(k\) | \(3k\) | \(3k^2\) | \(k^2\) | \(k^2+k\) |
Then the value of \(k\) is
