To find the value of n, we have to substitute n into 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11...
Now let's substitute n.
$${\mathtt{2}}{n} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}$$
In this situation, n = 3.
So, let's solve the problem.
$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}} = {\mathtt{6}}$$
So, $${\mathtt{6}}$$ is our answer.
