Answer 1

Answer: 52

Step-by-step explanation:

Answer 2

Answer:

Consider the numbers in the odd places i.e., 12, 21, 39, 75 .

The difference between first 2 of them is

21–12=9

Consider difference of next two odd places ,i.e.,

39–21=18 = 2×(previous answer)=2×9

Going like this,

The next one would be,

39+ (2×18)= 75. It is there in the question.

So, now going to the even places, the numbers are the double of their odd neighbours.

Impies,

12, (2×12), 21, (2×21), 39, (2×39), 75, (2×75)…

which is

12,24,21,42,39,78,75,150.

So, the next number in the series is 150.
