For this kind of problem, you want to multiply each of the numbers of options together. You'd say, there's 6 colors for each of 4 designs, which in turn are each in 3 different sizes. That's 6 * 4 * 3, which is 72 different T-shirts.

Answer:
D
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = - 3 , then
= 8 - 3(n - 1) = 8 - 3n + 3 = - 3n + 11 → D
