What is the explicit formula for this sequence? -17, -21, -25, -29, ...
A. an = (-17) + (n - 114
B. an = (-4) + (n - 1)(-17)
C. an = (-17) + (n - 1)(-4)
D. an = (-33) + (n-1)(-4)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
