Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 17
In each triangle, the number at the top is one less than the left number, multiplied by the right number. The first two triangles show the rule, and the third gives the missing number.
First triangle: \((13-1)\times6=12\times6=72\)
Second triangle: \((17-1)\times9=16\times9=144\)
Third triangle: \((15-1)\times\,?=238\), so \(?=\frac{238}{14}=17\)
