Codebusters Pattern Recognition Questions and Answer 1 — Questions and Answers

Question 1: What is the next number in the sequence: 2, 4, 8, 16, ___?

18
32 (Correct answer)
24
64

Correct answer: 32

This is a geometric sequence where each term is obtained by multiplying the previous term by 2. The pattern is 2 * 2 = 4, 4 * 2 = 8, 8 * 2 = 16. Following this rule, the next number in the sequence is 16 * 2 = 32.

Question 2: What comes next in the series: A, C, E, G, ___?

F
H (Correct answer)
I
J

Correct answer: H

The initial sequence A, C, E, G follows a pattern of skipping one letter in the alphabet (e.g., A to C, C to E). This corresponds to letters at odd positions (1st, 3rd, 5th, 7th). If the pattern then shifts to simply taking the next letter in the alphabetical order after 'G', then 'H' would be the correct continuation. This implies a change in the sequence's rule after the initial progression.

Question 3: Find the missing number in the sequence: 3, 9, 27, ___, 243

81 (Correct answer)
72
54
90

Correct answer: 81

This is a geometric sequence where each term is obtained by multiplying the previous term by 3. The pattern is 3 * 3 = 9, 9 * 3 = 27. Following this rule, the missing number is 27 * 3 = 81. The sequence then continues with 81 * 3 = 243, confirming the pattern.

Question 4: Which of the following comes next in the pattern: 1, 1, 2, 3, 5, 8,

10
12
13 (Correct answer)
21

Correct answer: 13

This is the Fibonacci sequence, where each number is the sum of the two preceding ones. The pattern starts with 1, 1. Then 1+1=2, 1+2=3, 2+3=5, 3+5=8. Following this rule, the next number in the sequence is 5 + 8 = 13.

Question 5: What is the next number in the sequence: 4, 6, 9, 6, 4, ___?

3 (Correct answer)
1
2
5

Correct answer: 3

This sequence appears to have a symmetrical or palindromic pattern. It starts with 4, 6, 9, then reverses or mirrors with 6, 4. The logical continuation of this mirroring would be the number that preceded the 4 in the reversed segment, which is 3, completing the symmetry (e.g., 3, 4, 6, 9, 6, 4, 3).
