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 figures I, II, and III are parts of a sequence. Which one of the following options comes next in the sequence at IV?
The axis of a parabola is parallel to the y-axis and its vertex is at \((5, 0)\). If it passes through the point \((2, 3)\), then its equation is:
Let \( f(x) = \log_e(x) \) and let \( g(x) = \frac{x - 2}{x^2 + 1} \). Then the domain of the composite function \( f \circ g \) is:
