1
Determine values or properties of numbers in a sequence when given a description of the sequence
ExampleIn a certain sequence where the numbers are increasing, the difference between consecutive terms is always the same. If the
term in the sequence is 
and the 
term is 
, what is the 
term in the sequence? -
2
Create and use ratios, fractions, or percents in solving problems
ExampleMarbles are to be removed from a jar that contains
red marbles and 
black marbles. What is the least number of marbles that could be removed so that the ratio of red marbles to black marbles left in the jar will be 
to 
? -
3
Solve more-complex counting problems (e.g., permutations, combinations, and inclusion/exclusion)
ExampleThere are
different ways to arrange the 
letters E, F, and G in a row from left to right. How many more ways are there to arrange the 
letters D, E, F, and G in a row from left to right?
