• Arithmetic Sequence: You get the next term by adding a constant value (the common difference, d) to the previous term.
  • Example: 2, 5, 8, 11, ... (here, d = 3)
  • The n-th term: a_n = a_1 + (n-1)d (where a_1 is the first term)
• Geometric Sequence: You get the next term by multiplying the previous term by a constant value (the common ratio, r).
  • Example: 3, 6, 12, 24, ... (here, r = 2)
  • The n-th term: a_n = a_1 * r^(n-1)

Geometry is all about shapes, their properties, and how they relate to each other. You'll work with both 2D shapes (like squares and circles) and 3D shapes (like cubes and spheres).

Functions are central to math. A function assigns each input value (from the domain) to exactly one output value (in the range). This "exactly one output" rule is crucial. If an input gives more than one output, it's not a function.
