What is the conclusion of inductive reasoning called, since it may or may not be correct?

• Theorem

• Postulate

• Conjecture

• Law

Which of the following is an example of inductive reasoning?

Which of this best describes deductive reasoning?

• It derives specific conclusions from general statements.

• It makes general statements based on specific observations.

• It does not require a logical foundation.

• It is only used in scientific experiments.

In which scenario is inductive reasoning being used?

• The number 2 is prime, the number 3 is prime, the number 5 is prime; therefore, all odd numbers are prime.

• If it rains, the ground gets wet. It is raining, so the ground must be wet.

• A rectangle has four sides; therefore, all four-sided figures must be rectangles.

• The speed of light is a constant, so any moving object cannot exceed this speed.

Which of the following best represents a counterexample?

• Every prime number is odd; however, 2 is a prime number that is even.

• The Earth is round, and all planets must be round.

• Since 3 × 5 = 15, all numbers are divisible by 5.

What pattern is observed in the sequence: 2, 4, 8, 16, 32, ...?

• Each number is obtained by adding 2 to the previous number.

• Each number is the result of subtracting 2 from the previous number.

• Each number is a multiple of 3.
