CFAT Problem Solving: Logical Reasoning 3

Question 1

What comes next in the sequence: 3, 6, 12, 24, ___?

Accepted Answer

48

Answer

Each term is doubled: 3×2=6, 6×2=12, 12×2=24, 24×2=48.

Question 2

Find the missing number: 2, 5, 10, 17, 26, ___

Accepted Answer

37

Answer

The differences increase by 2 each time (+3,+5,+7,+9,+11), so 26+11=37.

Question 3

What letter comes next: A, C, F, J, O, ___?

Accepted Answer

U

Answer

The gaps increase by one each step: +2, +3, +4, +5, +6; O is the 15th letter, and 15+6=21=U.

Question 4

Which number is next in the sequence: 100, 91, 83, 76, 70, ___?

Accepted Answer

65

Answer

The decrements shrink by one each step: −9,−8,−7,−6,−5, so 70−5=65.

Question 5

Which number does NOT belong in this sequence: 7, 11, 15, 19, 22, 27?

Accepted Answer

22

Answer

The sequence increases by +4 each time (7,11,15,19,23,27), so 22 is incorrect — it should be 23.
