The numbers in the right half form the series : On adding 1 in every term we get the next term as 2, 3, 4, 5.
The numbers in the left half form the series : On adding 2 in every term we get the next term as 5, 7, 9, ?.

Correct Option: B

The numbers in the right half form the series : On adding 1 in every term we get the next term as 2, 3, 4, 5.
The numbers in the left half form the series : On adding 2 in every term we get the next term as 5, 7, 9, ?.
∴ ? = 11

Clearly, we have : 7 x 2 + 2 = 16; 16 x 2 + 2 = 34 and so on.
So, missing number - 34 x 2 + 2 = ?

Correct Option: B

Clearly, we have : 7 x 2 + 2 = 16; 16 x 2 + 2 = 34 and so on.
So, missing number - 34 x 2 + 2 = ?
∴ ? = 70

Moving clockwise, we get the sequence :
2³ = 8,
3³ = 27 ,
4³ = 64,
..................

Correct Option: C

Moving clockwise, we get the sequence :
2³ = 8,
3³ = 27 ,
4³ = 64,
5³ = 125,
6³ = 216,
7³ = ?
∴ ? = 343
