A sequence lists the line thicknesses of a drawing as 1px, 2px, 4px, 8px, 16px. What is the thickness at step 6?

16px 24px 64px 32px

Correct Answer:

32px

Explanation:

The pattern doubles each step. Each term is obtained by multiplying the previous one by 2, so the sequence goes 1, 2, 4, 8, 16, and the next is 32. Using the formula a_n = a_1 × 2^(n−1), for step 6 you get 1 × 2^5 = 32. So the thickness at step 6 is 32px.
