Question

Find the missing number 6,3,24 8,64,48 7,4,?

Answer 1

If 6 becomes 3 (6 divided by 2), then 3 becomes 24 (6 x 4 = 24).
8 becomes 64 (8 x 8 = 64) then 64 becomes 48 (6 x 8 = 48) 
7 becomes 4 (7 - 3 = 4) then 4 becomes (6 x 12 = 72)

Answer 2

Missing number of the series 6,3,24 8, 64, 48 7,4 is 42

Solution:  

The given series is 6,3,24 8, 64, 48, 7, 4

Observe the series as follows:

1. Take first three numbers

2. Multiply first number with 2

3. Multiply the answer with second number

4. Subtract the answer with number 12

5. We can obtain the third number.

$\begin{array}{l}{6 \times 2=12,12 \times 3=36,36-12=24} \\ {8 \times 2=16,16 \times 4=64,64-16=48}\end{array}$

So, every third term is obtained as the difference of the values operated on first and second term.

Similarly, $7 \times 2=14,14 \times 4=56,56-14=42$

Therefore, the missing number is 42.
