Study Notes

Geometric Sequences and Fibonacci

11th term of the sequence with a first term of 9 and common ratio of 25 is 87,890,625.
Successive ratios of Fibonacci numbers approach the Golden Ratio, approximately 1.618.
Fibonacci, an Italian mathematician, is known for the Fibonacci sequence.

Sets and Logic

Intersection of sets X, Y, and Z is the empty set.
For sets A = {3, 5, 7, 9} and B = {2, 4, 6, 8, 10, 12}, set C = {2, 4, 8, 12} is a subset of B.
Confirmed subset relationships: Set B is a subset of set A.

Sequences and Patterns

Next terms in the sequence AZ, CX, EV, GT are IR and KP.
The 18th term of the sequence 5, 3, 1, -1, … is -29.
Determine the next term in the sequence A5, D25, G125, J625, M3125 is P15625.
Continuing the pattern in 1, 14, 51, 124, 245, 426, the next number is 679.

Mathematical Properties and Functions

The angle of rotation for an object with 18-fold symmetry is 20 degrees.
The domain of function f(x) = 2/x + 3 cannot include x = -3.
For relation {(8,11),(3,5),(6,17),(x,22)} to be a function, x must equal 22.

Mathematical Language

"The product of the sum and difference of two numbers is the difference of the square of two numbers" translates to (a + b)(a - b) = a² - b².
Nature of mathematics emphasizes conciseness and precision in expressing thoughts.
Half of a number being the sum of five and that number becomes x/2 = 5 + x in mathematical terms.

Combinatorial and Summation Principles

Least common multiple of 5, 2 and 7 is 70.
Mathematical notation for summation of numbers is ∑.
The commutative property is illustrated by 2 + 5 = 5 + 2.

Reasoning Types

Deductive reasoning is demonstrated through syllogisms (e.g., all women are mortal; Gregoria De Jesus is a woman, thus mortal).
Inductive reasoning involves deriving generalized conclusions from specific examples.

Clock and Symmetry

The angle between clock hands at 3:40 is 130 degrees.
Rotational symmetry is when an object appears unchanged after a rotation.

Additional Notes

A complete set of ordered pairs defines a relation.
The concept of a sequence pertains to an ordered arrangement of numbers or objects.
