Answer 1

ANSWER

8,24,16,?,7,14,6,18,12,5,5,10

If we see the given pattern, we can find out that every alternative digit is related, For instance, 

For all odd consecutive series; 

8×2=16,?×2=14,6×2=12,5×2=10

For 3rd and fourth , six and seventh , ninth and tenth relation are as follows respectively; 

?×2+2=16,6×2+2=14,5×2+2=12

or if we simplify the above;

we get ? = 7 and 7×2+2=14
