The sum of digits of the previous number is added to the next number.

1 + 9 = 10 -> 19 + 10 = 29

2 + 9 = 11 -> 29 + 11 = 40

4 + 0 = 4 -> 40 + 4 = 44

4 + 4 = 8 -> 44 + 8 = 52

=> Ans – (B)

Thus, missing number = 73

=> Ans – (A)

All the numbers are multiplied by 4.

Thus, missing number = 192

=> Ans – (C)

The pattern followed is for the alternate terms is :

Thus, missing number = 11

=> Ans – (B)

The previous number is multiplied.

4 $\times3$ = 12

12 $\times4$ = 48

48 $\times12$ = 576

=> Ans – (B)

The pattern followed is :

Thus, missing number = 37

=> Ans – (C)

Series of cubes of successive prime numbers.

$2^3$ = 8

$3^3$ = 27

$5^3$ = 125

$7^3$ = 343

$11^3$ = 1331

=> Ans – (C)

The pattern followed is :

Thus, missing number = 33

=> Ans – (B)

The pattern followed is :

Thus, missing number = 484

=> Ans – (A)

The pattern followed is :

Thus, missing term = 107

=> Ans – (C)

The pattern followed is that squares of natural numbers in decreasing order are given.

Thus, missing term = 169

=> Ans – (C)

The pattern followed is :

Thus, missing term = 294

=> Ans – (A)

The pattern followed is that each number is multiplied by 5 and then 5 is added.

Thus, missing term = 3905

=> Ans – (B)

The pattern followed is :

Thus, missing term = 402

=> Ans – (C)

The pattern followed is :

8 $\times3-3$ = 21

21 $\times3-3$ = 60

60 $\times3-3$ = 177

177 $\times3-3$ = 528

=> Ans – (B)
