Find nth-term rule from a sequence

Finding the nth-Term Rule

Find the expression for a sequence, then use it to calculate a distant term or term position.

Start practicing →
3n + 2 produces sequence terms 5, 8, 11

Calculating Terms Using the nth-Term Rule

Use a given nth-term rule to find three terms, progressing from positive expressions to negative numbers, brackets, and like terms.

Start practicing →
Equation with variable terms on both sides

Equations with Variables on Both Sides

Solve linear equations with variable terms on both sides, progressing from straightforward positive integers to combining like terms, negatives, and decimal coefficients.

Geometric pattern with a missing term and a constant common ratio

Common Ratio in Patterns

Find missing terms in geometric patterns by multiplying by the same common ratio, progressing from whole-number growth to decay, negative ratios, and decimals.

Start practicing →
Arithmetic pattern with a missing term and a constant difference

Common Difference in Patterns

Find missing terms in arithmetic patterns by using the same common difference between consecutive terms, from whole-number patterns to negatives and decimals.

Algebraic expression 3x plus 5 with x equal to 4 being evaluated

Evaluating Algebraic Expressions

Substitute given values into algebraic expressions and calculate through Foundation, Core, and Challenge.

Start practicing →
Two-step equations using a coefficient and a fraction coefficient

Two-Step Equations

Choose Coefficient + Constant, Fraction Coefficient, or Mixed, then solve two-step equations through Foundation, Core, and Challenge.

Start practicing →
3(x + 2) = 2x + 11

Equations with Brackets

Expand brackets, simplify both sides, and isolate the variable across Foundation, Core, and Challenge modes.

Start practicing →
3x + 2y − x
