Question:
$x=1,2,3,4,5,6$ give $y=4,8,14,22,32,44$. Find relation $y$ vs $x$.
$x=1,2,3,4,5,6$ give $y=4,8,14,22,32,44$. Find relation $y$ vs $x$.
Show Hint
If second differences are constant, the sequence follows a quadratic relation.

- $y = a + bx$
- $y = a + bx + cx^2$
- $y = e^{a+bx}$
- None
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Check differences:
First diff: $4,6,8,10,12$ — increases by constant 2, so quadratic fits.
\[
\boxed{y = a + bx + cx^2}
\]
