Answer: 30
Explanation The first 5 multiples of 5 are 5, 10, 15, 20, and 25. These can be written as: 5 × 1 = 5 5 × 2 = 10 5 × 3 = 15 5 × 4 = 20 5 × 5 = 25 5*6=30
Answer: L
Explanation The given series is formed by increasing the letters by skipping one letter each time: D (+2) -> F (+2) -> H (+2) -> J Following the same pattern, the next letter after J, skipping one letter, would be L. So, the next letter in the series is: L.
Answer: 9
Explanation Firstly we have to find the pattern of the sequence, In the same way, if we take the missing term as 3, 8, 6, 17, ?, 20 3 x 2 + 2 = 8 6 x 2 + 2 = 14 a x 2 + 2 = 20 a x 2 = 18 a = 18/ 2 a = 9 ND-21-5-2023
Answer: 15
Explanation The series alternates between subtracting 1 and adding 2: 12 → 11 (subtract 1) 11 → 13 (add 2) 13 → 12 (subtract 1) 12 → 14 (add 2) 14 → 13 (subtract 1) Following this alternating pattern, the next step should be adding 2 to 13: 13 + 2 = 15 13 + 2 = 15
Answer: 28
Explanation Let's analyze the pattern: 40 - 5 = 35 35 - 4 = 31 31 - 3 = 28 28 - 2 = 26 26 - 1 = 25 The pattern involves subtracting decreasing numbers (5, 4, 3, 2, 1).
Answer: 31
Explanation Check the difference between terms: 11 - 7 = 4 19 - 11 = 8 So, the pattern in differences: +4, +8, +12... Next difference: +16 So, 19 + 16 = 35 Oops! That gives 35, not 31. Let's try again: Actually: 7 → 11 → 19 → ? Differences: 11 - 7 = 4 19 - 11 = 8 So next difference = +12 19 + 12 = 31
Answer: 19
Explanation The pattern shows an increase of 2 in each number. After 17 , the next number is 19 .
Answer: 15
Explanation (10 + 20) ÷ 2 = 15
Answer: 12, 180, 228
Explanation 11 × 15 = 165 11 × 19 = 209 12 × 15 = 180 11 × 19 = 228
