Question

Raghav reaches late to school $3$ days in a week. The number of days he is late in $x$ weeks is ______ .

Answer 1

Explanation:

In the first week the number of days Raghav is late is $3$days, in the second week it will again be $3$days which adds upto $6$days ($3\times 2$).

Similarly in the third week the total days Raghav will be late is $9\left(3\times 3\right)$.

Following the pattern, in $x$weeks the total days Raghav will be late will be $3x$.

Hence, Raghav reaches late to school $3$ days in a week. The number of days he is late in $x$ weeks is $\underline{3x}$.
