Complete the table and hence find the solution of the given equation:
$\frac{n}{8}=5$

Solve the following equation by balancing the equation:

$x-6=4$

Solve the following equation by balancing the equation:

$y+5=10$

Find the value of $m$ for the equation: $2m=16$.

Look at the matchstick pattern given below for letter $\mathrm{N}$:

Generalise a rule for the number of matchsticks required for making $x$ number of $\mathrm{N}$s. Also find out how many matchsticks are required for making $12 \mathrm{N}$s.

If the rule used to create the number pattern shown below is of the form, $\text{Next number}=\frac{\text{Previous number}}{2}+K$, then find the value of $K$.

$250, 130, 70, 40, 25$
