220
222
224
230
ExplanationThe pattern is (previous number * 2) + 2. So, 110 * 2 + 2 = 222, but the intended pattern is 2*n + 2. Wait, the pattern is n * 2 + 2: 5*2 + 2 = 12; 12*2 + 2 = 26; 26*2 + 2 = 54; 54*2 + 2 = 110 (Incorrect). The correct pattern is (previous number * 2) + 2. Let's recheck: 5*2 + 2 = 12; 12*2 + 2 = 26; 26*2 + 2 = 54; 54*2 + 2 = 110. This is consistent. Next number: 110 * 2 + 2 = 220 + 2 = 222. Let's re-examine the options and series carefully. If the series is 5, 12, 26, 54, 110. Differences: 7, 14, 28, 56. The multiplier is 2. Next difference: 56 * 2 = 112. 110 + 112 = 222. Re-checking the options, 222 is B. There might be a typo in the provided options or question itself. Assuming 222 is the correct answer based on the difference pattern (n * 2 + 2). If we stick strictly to the options provided and assume one of them is correct: The sequence is 5, 12, 26, 54, 110. The differences are 7, 14, 28, 56. The next difference must be 112. 110 + 112 = 222. Given the constraint to choose one of the provided options, let's assume there was a typo in the question's given options and select B: 222.
38
39
42
40
ExplanationThe difference between consecutive terms increases by 2 (3, 5, 7, 9, 11). Therefore, the next number is 27 + 11 = 38.

95
101
97
93
ExplanationThe pattern is multiplying the previous number by 2 and adding 1 ($n imes 2 + 1$). The next number is $47 imes 2 + 1 = 95$.
35
40
37
30
ExplanationThe pattern involves adding consecutive odd squares (3^2, 5^2, 7^2...). The next number is 37 (26 + 11 = 37).
36
31
35
34
ExplanationThis is a Fibonacci sequence where each number is the sum of the two preceding numbers (5+8=13; 8+13=21; 13+21=34). Wait, the next number is 21+13=34. The pattern is 2, 3, 5, 8, 13, 21, 34. Since 34 is an option, we select (B). (Correction based on re-evaluation: The pattern is Fibonacci. 21 + 13 = 34. Thus, 34 is the answer.)
40
38
37
39
ExplanationThe pattern is based on squares plus one (n^2 + 1). The next number is 6^2 + 1 = 36 + 1 = 37. Wait, the gap suggests n^2 + 1. Let's check the difference: 3, 5, 7, 9. The next difference must be 11. So, 26 + 11 = 37. (Correction: Let's re-evaluate the series: 2, 5, 10, 17, 26. Differences: 3, 5, 7, 9. The next difference is 11. So, 26 + 11 = 37.)
55
63
47
64
ExplanationThis is a powers of two minus one sequence (2^n - 1). The next number is 2^6 - 1 = 63.
95
92
101
99
ExplanationThe difference between consecutive terms doubles each time (+3, +6, +12, +24). The next difference must be 48. Therefore, 47 + 48 = 95.
131
95
128
127
ExplanationThe pattern involves doubling the previous term and adding 1 (N * 2 + 1). The next number is 63 * 2 + 1 = 127.
149
169
139
159
ExplanationThe pattern involves multiplying the previous number by 2 and adding 1, then adding 2 to the result. (4*2+1+3 = 12, but this is simpler: (9-4)*2+9 = 18, this pattern is (n*2 + n-1)). The difference between consecutive terms is 5, 10, 20, 40. The next difference is 80. 79 + 80 = 159.
112
108
102
110
