Answer: 905
Explanation Each number increases by 201 : 302 − 101 = 201 503 − 302 = 201 704 − 503 = 201 So, 704 + 201 = 905 .
Answer: 57
Explanation Odd positions (1st, 3rd, 5th): 17, 51, 3 - 17 × 3 = 51 - 51 ÷ 17 = 3 Pattern: ×3, ÷17 Even positions (2nd, 4th, 6th): 2, 19, ? - 19 − 2 = 17 - So: 2 → +17 → 19 - 19 → +38 → 57 Seems it's increasing by: +17, +38... (difference increasing by 21) So the 6th number is 57

Answer: 22.12
Explanation We could not notice any common pattern in the above series On close observation we notice that it is a combination of two series We shall take the terms only at odd-numbered positions and analyse the pattern first Now we shall take the numbers at even-numbered positions and analyse the pattern 2 3 5 7 11 ____ The terms are consecutive prime numbers Hence the missing number in this series is 13 which is the next prime number This type of series is called twin series or combination/mixed series Ans :- 11, 13.
Answer: 20
Explanation The series increases by 5 each time: 5 → 10 (+5) 10 → 15 (+5) 15 → 20 (+5) So, the next number is 20.
Answer: R
Explanation The pattern followed here is:- Z - 2 = X X - 2 = V V - 2 = T T - 2 = R Hence, the correct answer is "R" .
Answer: 32
Explanation 22 → 25 → 27 → 30 Differences between terms: - 25 - 22 = 3 - 27 - 25 = 2 - 30 - 27 = 3 The pattern alternates: +3, +2, +3, +2... So, the next difference should be +2. 30 + 2 = 32
Answer: 127
Explanation The pattern of the sequence is obtained by adding 2, then 4, then 8, then 16, and so on (doubling the previous addition). Therefore, the next number in the sequence would be: 1 + 2 = 3 3 + 4 = 7 7 + 8 = 15 15 + 16 = 31 31 + 32 = 63 63 + 64 = 127 So, the correct answer is: 127
Answer: 91
Explanation The pattern of the sequence appears to be formed by adding consecutive increments: 1 + 4 = 5 5 + 9 = 14 14 + 16 = 30 30 + 25 = 55 55 + 36 = 91 The next term in the sequence would be 91 .
Answer: 8: 1
Explanation =-2000÷10 : 250÷10 = 200÷5 : 25 ÷ 5 = 40÷5 : 5÷5 = 8:1
Answer: 155
Explanation 180 - 55 = 155
