$\begin{vmatrix}109&102&95\\6&13&20\\1&-6&-13\end{vmatrix}$ is equal to
Answer & explanation
Correct answer: option 2
Since elements of the rows are in A.P. with common difference 7, the given determinant is zero (Operations C1 - C3 and C2 - C3 make the elements in C1 and C2 proportional).
Hence (B) is the correct answer.
