Question 1:

Which rule or principle is followed by the following sequence of shapes?

Sequence: Circle, Square, Triangle, Circle, Square

Explanation: The correct answer is B) Alternating shapes. The sequence follows an alternation between a Circle and a Square. Therefore, the rule followed is alternating shapes.

Question 2:

Which rule or principle is followed by the following sequence of numbers?

Sequence: 2, 4, 8, 16, 32

Explanation: The correct answer is A) Multiplication by 2. Each number in the sequence is obtained by multiplying the previous number by 2. For example, 2 * 2 = 4, 4 * 2 = 8, and so on. Therefore, the rule followed is multiplication by 2.

Question 3:

Which rule or principle is followed by the following sequence of letters?

Sequence: A, E, I, M, Q

Explanation: The correct answer is D) Skipping four letters in the alphabet. Each letter in the sequence is obtained by skipping four letters in the alphabet. For example, A + 4 = E, E + 4 = I, and so on. Therefore, the rule followed is skipping four letters in the alphabet.

Question 4:

Which rule or principle is followed by the following sequence of colors?

Sequence: Red, Blue, Yellow, Green, Orange

Explanation: The correct answer is A) Alternating between primary and secondary colors. The sequence follows an alternation between primary colors (Red, Yellow) and secondary colors (Blue, Green). Therefore, the rule followed is alternating between primary and secondary colors.

Question 5:

Which rule or principle is followed by the following sequence of numbers?

Sequence: 1, 3, 6, 10, 15

Explanation: The correct answer is C) Addition by 3. Each number in the sequence is obtained by adding the next natural number. For example, 1 + 2 = 3, 3 + 3 = 6, and so on. Therefore, the rule followed is addition by 3.
