300 test results are integers ranging from 15 to 75, inclusive. Dominick’s result is clearly in the 80th percentile of those results, not the 79th or the 81st.

List L consists of the 7 numbers u,-2u,-3u,-4u,-5u,-6u, and -7u, where u≠0.

a₁,a₂,a₃,....a_n,...

In the sequence above, a₁=1 and for each term after the first term, a_n=()a_n−1

For each positive integer n, a_n=

A certain sequence is defined by the formula a_n=a_n–1–7. a7=7

2,7, …, 247 is an arithmetic sequence.

.25, .5, .75, 1, 1.25, 1.5, 1.75, 2.....

In the sequence of numbers a₁,a₂,a₃....,a_n......is defined by an= for each integer n≠1

.25, .5, .75, 1, 1.25, 1.5, 1.75, 2, . . .

S_n=3n+3
Sequence S is defined for each integer n such that
0 < n < 10,000.
