Answer: 10,50
Explanation ***** ND04-12-2022
Answer: 84
Explanation The given series is: 14, 28, 42, 56, 70, ? This is an arithmetic progression with a common difference of 14: - 14 + 14 = 28 - 28 + 14 = 42 - 42 + 14 = 56 - 56 + 14 = 70 - 70 + 14 = 84
Answer: V
Explanation The letter that comes next in the series D, G, K, P is V. The pattern involves increasing the gap between consecutive letters by one each time: D (+3) G (+4) K (+5) P (+6) V.
Answer: 57
Explanation The pattern of the number series appears to be an increase of 5, 4, 9, 13, ... , which suggests an increase of 4, then 9, then 13, and so on. Therefore, the next increase would be 15 , which adds up to 57 . Here's the completed series: 4, 9, 13, 22, 35, 57
Answer: 74
Explanation 3 × 2 + 1 = 7 7 × 2 + 2 = 16 16 × 2 + 3 = 35 35 × 2 + 4 = 74 74 × 2 + 5 = 153

Answer: 2500
Explanation The sum of odd integers from 1 to 100 are - 1 + 3 + 5 + 7 + ……… + 99. This is an Arithmetic Progression with the following parameters: First Number, a = 1 Last Number, l = 99 Common Difference, d = 2 So, the Number of terms in the Arithmetic Progression, n = (l - a)/d + 1 = (99 - 1)/2 + 1 = 98/2 + 1 = 49 + 1 = 50 So, the sum of the Arithmetic Progression, S = n/2(l + a) = 50/2(99 + 1) = 25 X 100 = 2500 So, the sum of odd integers from 1 to 100 = 2500
Answer: 6
Explanation Step 1: Identify the pattern Find the differences between consecutive terms: 21 - 20 = 1 20 - 18 = 2 18 - 15 = 3 15 - 11 = 4 The pattern of differences is: +1, +2, +3, +4 Step 2: Find the next difference The next difference should be +5 11 - 5 = 6
Answer: 48
Explanation Series: 7, 9, 12, 17, 24, 35, ? Step 1: Find differences 9 − 7 = 2 12 − 9 = 3 17 − 12 = 5 24 − 17 = 7 35 − 24 = 11 Differences: 2, 3, 5, 7, 11 → all prime numbers. Step 2: Next prime after 11 = 13 Step 3: Add to last term 35 + 13 = 48
Answer: 15016
Explanation The first digit is formed by adding the numbers which are the results of powers of 2 increased by one and second letter is the corresponding alphabet to that number...last number is the next number to the first one...therefore 15=7+8(i.e.2^ 3 ) O is corresponding alphabet to 15 and 16 comes after 15 ND-21-5-2023
