ICET Logical Reasoning

Question 1

What is the next number in the series: 2, 6, 12, 20, 30, ?

Accepted Answer

42

Answer

The differences between consecutive terms are 4, 6, 8, 10, 12 (increasing by 2 each time), so the next term is 30 + 12 = 42.

Question 2

Find the next term in the letter series: A, C, F, J, O, ?

Accepted Answer

U

Answer

The gaps between letters increase by 1 each time (2, 3, 4, 5, 6), so the next letter is O + 6 positions = U.

Question 3

BOOK is to LIBRARY as PAINTING is to ___.

Accepted Answer

Museum

Answer

Just as a book is stored and displayed in a library, a painting is stored and displayed in a museum.

Question 4

Which number does NOT belong in the group: 2, 3, 5, 7, 9, 11?

Accepted Answer

9

Answer

9 = 3 × 3, making it a composite number, while 2, 3, 5, 7, and 11 are all prime numbers.

Question 5

A is the brother of B. B is the sister of C. C is the father of D. How is A related to D?

Accepted Answer

Uncle

Answer

A and B are siblings, B and C are siblings, so A and C are siblings; since C is D's father, A (a male sibling of D's father) is D's uncle.
