Number of television Buyers in 1982 = 447
Number of Television buyers in 1984 = 458 (447+11)
Number of Television buyers in 1986 = 489 (458+ 11 +20)
Number of Television buyers in 1988 = 540 (489 + 11 +20 +20 )
Number of Television buyers in 1990 = 611 (540 + 11 +20 +20 + 20 )

The pattern followed is :

Thus, $24^2=576$

=> Ans – (B)

The pattern followed is :

Thus, missing number = 42.5

=> Ans – (A)

The pattern followed is :
60 ×2 + 1 = 121
121 ×2 + 1 = 243243 ×2 + 1 = 487
=> Ans – (B)

The pattern followed is :

Thus, missing number = 364

=> Ans – (C)

The pattern followed is :

Thus, missing number = 1440

=> Ans – (A)

The pattern followed is :

$(11)^2+1$ = 122

$(14)^2+1$ = 197

$(17)^2+1$ = 290

$(20)^2+1$ = 401

=> Ans – (C)

The pattern followed is :

Thus, missing number = 340

=> Ans – (B)

Expression : 30, 60, 360, 3600, ?

Thus, missing number = 50400

=> Ans – (C)

The pattern followed is :

Here 2+3=5 , 3+5=8 , 5+8=13 , 8+13=21

Thus, missing number = 441

=> Ans – (A)

The pattern followed is :

Thus, missing number = 84

=> Ans – (B)

Consecutive integers are multiplied.

12 $\times2$ = 24

24 $\times3$ = 72

72 $\times4$ = 288

288 $\times5$ = 1440

=> Ans – (A)

Cubes of consecutive natural numbers are added.

13 $+2^3$ = 21

21 $+3^3$ = 48

48 $+4^3$ = 112

112 $+5^3$ = 237

=> Ans – (A)

17 + 10 = 27

27 + 15 = 42

42 + 20 = 62

62 + 25 = 87

=> Ans – (B)
