The order of above series is given as
First term = 7
Second term = First term x 2 +9
Third term = Second term x 2 +11
Similarly we can calculate next terms also.

Correct Option: B

The order of above series is given as
First term = 7
Second term = ( First term x 2 ) +9
⇒ Second term = ( 7 x 2 ) + 9 = 14 + 9 = 23
Third term = ( Second term x 2 ) +11
⇒ Third term = ( 23 x 2 ) + 11 = 46 + 11 = 58 is wrong , 57 should be Third term because ( 23 × 2 ) + 11 = 57 .
Similarly we can find all others terms also.
Fourth term = ( Third term x 2 ) +13
⇒ Fourth term = ( 57 x 2 ) +13
Fifth term = ( Fourth term x 2 ) +15
⇒ Fifth term = ( 127 × 2 ) + 15 = 269
Sixth term = ( Fifth term x 2 ) +17
⇒ Sixth term = ( 269 × 2 ) + 17 = 555

From the above given series , we have
First term + 350 = Second term
⇒ 156 + 350 = 506
Second term + 550 = third term
⇒ 506 + 550 = ? ⇒ ? = 1056

Correct Option: A

From the above given series , we have
First term + 350 = Second term
⇒ 156 + 350 = 506
Second term + 550 = third term
⇒ 506 + 550 = ? ⇒ ? = 1056
From the given figure , we get the value of third term ( ? ) = 1056
Third term + 550 = Fourth term
⇒ 1056 + 750 = 1806

See the below image and find the pattern to solve this question.

Correct Option: D

See the below image and you will find a pattern in which numbers are getting added for next number in the given series.
From the given figure , we get the value of sixth term ( ? ) = 69

See the graph and found that the given number in the series with specific pattern.
From the given graph , we can see that the increasing order of series as -
First term = 2
Second term = First term + 1 = 3 ,
Third term = Second term x 2 = 6
Similarly , we can calculate all others terms also.

Correct Option: B

See the graph and found that the given number in the series with specific pattern.
From the given graph , we can see that the increasing order of series as -
First term = 2
Second term = First term + 1 = 2 + 1 = 3 ,
Third term = Second term x 2 = 3 x 2 = 6 ,
Fourth term = Third term + 1 = 6 + 1 = 7 ,
Fifth term = Fourth term x 2 = 7 x 2 = 14 ,
Sixth term = Fifth term + 1 = 14 + 1 = 15 ,
Seventh term = Sixth term x 2 = 15 x 2 = 30
∴ Seventh term( ? ) = 30

According to position of alphabets in alphabet table , we have
B C F G → 2 , 3 ,6 , 7
J K N O → 10 , 11 , 14 , 15
R S V W → 18 , 19 , 22 , 23
{ ∴ Next sequence = Adding 8 in every position of previous sequence alphabets }

Correct Option: A

According to position of alphabets in alphabet table , we have
B C F G → 2 , 3 ,6 , 7
J K N O → 10 , 11 , 14 , 15
R S V W → 18 , 19 , 22 , 23
{ ∴ Next sequence = Adding 8 in every position of previous sequence alphabets }
Next sequence = 18 + 8 , 19 + 8 , 22 + 8 , 23 + 8
Next sequence = 26, 27, 30, 31 = 26, 27 - 26 = 1, 30 - 26 = 4, 31 - 26 = 5 = Z A D E ( subtract the excess value by 26 )
We get , 26 , 1 , 4 , 5 → Z A D E = ( ? ) .
