Geometry and Algebra Concepts Assessment

The video covers a range of geometry topics, including analyzing triangles and quadrilaterals, calculating area and perimeter, rotating shapes, writing equations for sequences, and setting up geometric proofs. It also includes a multiple-choice question analysis.

What is the common difference in the arithmetic sequence where the first term is -30 and the second term is -15?

• -30

• 30

• -15

• 15

How do you express a geometric sequence with an initial term of 27 and a common ratio of 1/3?

• T(n) = 27 * (1/3)^n

• T(n) = 27 * n^3

• T(n) = 27 / 3^n

• T(n) = 27 + (1/3)^n
