The given sequence is \( 6, 9, 14, x, 30, 41 \). Calculate the differences between consecutive terms:
\[ 9 - 6 = 3, \quad 14 - 9 = 5. \]Let \( x \) be the next term:
\[ x - 14 = 7 \quad \Rightarrow \quad x = 21. \]For the subsequent terms:
\[ 30 - 21 = 9, \quad 41 - 30 = 11. \] Step 2: Confirm the pattern.The differences between consecutive terms form the sequence:
\[ 3, 5, 7, 9, 11. \]This is an arithmetic progression with a common difference of \( 2 \), verifying the correctness of the solution.
Thus, the value of \( x \) is \( \boxed{21} \).

The \( F_{121} \) value of a known microorganism with \( Z \) value of \( 11^\circ C \) is 2.4 min for 99.9999% inactivation. For a 12D inactivation of the said microorganism at \( 143^\circ C \), the \( F \) value (in min) is .......... (rounded off to 3 decimal places)
Three villages P, Q, and R are located in such a way that the distance PQ = 13 km, QR = 14 km, and RP = 15 km, as shown in the figure. A straight road joins Q and R. It is proposed to connect P to this road QR by constructing another road. What is the minimum possible length (in km) of this connecting road?
Note: The figure shown is representative.
For the clock shown in the figure, if
O = O Q S Z P R T, and
X = X Z P W Y O Q,
then which one among the given options is most appropriate for P?
