Answer: 36
Explanation 60 days = 15 men 1 day = 60*15 = 900 men 25 days = 900/25 = 36 men
Answer: IJ/q
Explanation First pair’s first letters jump by +4 : A→E→I→M ⇒ pairs AB, EF, IJ, MN . Letters after the slash go +2 in alphabet positions: m(13), o(15), q(17), s(19) . So the missing term is IJ/q .

Answer: 36
Explanation 1, 4, 9, 16, 25 is the sequence of the squares of the natural numbers. Therefore, 6^2 = 36 will be the next number in the sequence.
Answer: 1
Explanation The pattern in the sequence appears to be obtained by dividing the previous term by 3: 27 ÷ 3 = 9 9 ÷ 3 = 3 3 ÷ 3 = 1
Answer: 25
Explanation Step 1: Find the pattern 5 − 1 = 4 9 − 5 = 4 13 − 9 = 4 17 − 13 = 4 21 − 17 = 4 The series increases by 4 each time. Step 2: Find the next term Next number = 21 + 4 = 25
Answer: 24
Explanation - Looking at the series, we can see that the numbers are increasing with some common differences between them. - The pattern is as follows : - 6 + 3 = 9 - 9 + 6 = 15 - 15 + 6 = 21 - 21 + 3 = 24 - 24 + 4 = 28 - 28 + 2 = 30 By observing the pattern , we can see that all numbers follow an increment by either 3 or 6, except for 24, which increases by 4 instead of 3 or 6. Therefore, the o dd man out i n the series is 24.
Answer: 116
Explanation Let's analyze the differences between consecutive terms: 20 - 11 = 9 35 - 20 = 15 56 - 35 = 21 83 - 56 = 27 The differences are increasing by 6 each time. So, the next difference should be 27 + 6 = 33. Therefore, the next term in the series is 83 + 33 = 116.
Answer: 18
Explanation Find the differences between consecutive terms: 7 – 3 = 4 12 – 7 = 5 Differences increase by 1 each time: 4, 5, … → next difference = 6 Next number = 12 + 6 = 18
Answer: 90
Explanation The pattern follows: +12, +13, +14, +15, +16 74 + 16 = 90
Answer: -1
Explanation The pattern in the series appears to be a decrease of 1, then an increase of 3, repeating: 7 -> 6 (decrease by 1) 6 -> 5 (decrease by 1) 5 -> 9 (increase by 3) 9 -> 3 (decrease by 6, but pattern suggests decrease by 1) 3 -> 12 (increase by 3) 12 -> 1 (decrease by 11, but pattern suggests decrease by 1) 1 -> 15 (increase by 3) 15 -> -1 (decrease by 1) Therefore, the next number in the series is -1.
