Number Sequence | MCQs

Explanation

The pattern in the series is a decrease of 4, 8, 4, 2, ... (alternating between subtracting 4 and 8, then decreasing the subtraction by 2 each time).

Therefore, the next number in the series would be:

• 64 - 16 (4 + 8 + 4) = 48
• 48 - 8 (4 + 4) = 40
• 40 - 4 (4) = 36
• 36 - 2 (2) = 34
• 34 - 1 (1) = 33

So, the correct answer is: 33

Explanation

• 3 + 2 = 5
• 5+ 2 = 7
• 7+ 3= 10
• 10 + 2 = 12
• 12 + 2 = 14
• 14+ 10 = 24
• 24 + 2 = 26
• 26 + 2 = 28
  

Explanation

So in this way the next number in the sequence, 0, 3, 8, 15, 24, 35

From the given series the logic is adding odd numbers in the series

0 + 3 = 3

3 + 5 = 8

8 + 7 = 15 

15 + 9 = 24

24 + 11 = 35

Explanation

Given information:

1. The average of the first three numbers (A, B, C) is 15

   $$frac{A + B + C}{3} = 15$$ $$A + B + C = 45$$

2. The average of the last three numbers (B, C, D) is 16

   $$frac{B + C + D}{3} = 16$$ $$B + C + D = 48$$

3. The last number (D) is 19

   $$B + C + 19 = 48$$ $$B + C = 29$$

Finding A

We already have:

$$A + B + C = 45$$

Substituting $B + C = 29$:

$$A + 29 = 45$$$$A = 45 - 29$$ $$A = 16$$

7×7=49,

5, 

5 x 5 = 25

Explanation

The logic is: 4 × 1 = 4

4 × 2 = 8

8 × 3 = 24

24 × 4 = 96

96 × 5 = 480
