The first figure of the sierpinski triangle has one shaded triangle. the second figure of the sierpinski triangle has three shaded triangles. the third figure of the sierpinski triangle has nine shaded triangles. which summation represents the total number of shaded triangles in the first 15 figures?

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
