Q:

# Find the missing number in the series?4, 18, ?, 100, 180, 294, 448

 A) 48 B) 50 C) 58 D) 60

Explanation:

Take a Look at this series :

$23$ - $22$ =  8 - 4 = 4

$33$ - $32$ = 27 - 9 = 18

$43$ - $42$ = 64 - 16 = 48

$53$ - $52$ = 125 - 25 = 100

$63$ - $62$ = 216 - 36 = 180

$73$ - $72$ = 343 - 49 = 294

$83$ - $82$ = 512 - 64 = 448

Q:

3, 6, 17.5, 64.75, ?

 A) 304.587 B) 295.875 C) 115.246 D) 101

Explanation:

3

3 x 1.5 + 1.5 = 6

6 x 2.5 + 2.5 = 17.5

17.5 x 3.5 + 3.5 = 64.75

64.75 x 4.5 + 4.5 = 295.875

Q:

Find the next number in the given sequence?

1, 2, 6, 21, 88, ?

 A) 445 B) 364 C) 296 D) 194

Explanation:

The given series is 1, 2, 6, 21, 88, ?

1

1 x 1 + 1 = 2

2 x 2 + 2 = 6

6 x 3 + 3 = 21

21 x 4 + 4 = 88

88 x 5 + 5 = 445

Hence, the next number in the given number sequence is 445.

Q:

Find the next number in the series given 18, 90, 450, 2250, ?

 A) 4520 B) 6520 C) 7250 D) 11250

Explanation:

The given number series is 18, 90, 450, 2250, ?

18

18 x 5 = 90

90 x 5 = 450

450 x 5 = 2250

2250 x 5 = 11250

Hence, the next number in the given series is 11250.

Q:

In following question, a number series is given with one term missing. Choose the correct alternative for these sequence.

24, 60, 120, 210, ?

 A) 336 B) 330 C) 300 D) 370

Explanation:

3 x 3 x 3 = 27 - 3 = 24

4 x 4 x 4 = 64 - 4 = 60

5 x 5 x 5 = 125 - 5 = 120

6 x 6 x 6 = 216 - 6 = 210

7 x 7 x 7 = 343 - 7 = 336

Q:

What would be the next number in the sequence 52, 56, 48, 64, 32, ?

 A) 96 B) 48 C) 54 D) 81

Explanation:

The given number series is 52, 56, 48, 64, 32, …

It follows a pattern that,

52

52 + 4 = 56

56 - 8 = 48

48 + 16 = 64

64 - 32 = 32

32 + 64 = 96

Therefore, the required next number in the given number series is 96.

Q:

Find the next number in the given series?

118, 166, 190, 202, 208, ?

 A) 211 B) 222 C) 233 D) 244

Explanation:

The given series is 118, 166, 190, 202, 208, ?

118

118 + 48 = 166

166 + 24 = 190

190 + 12 = 202

202 + 6 = 208

208 + 3 = 211

2 1275
Q:

2, 16, 3, 81, 4, ?

 A) 99 B) 125 C) 256 D) 396

Explanation:

The given number series is 2, 16, 3, 81, 4, ?

2

2^4 = 16

3

3^4 = 81

4

4^4 = 256

Hence, the next number is 256.

2 496
Q:

Find the next number in the given number sequence

200, 200, 100, 300, 75, ?

 A) 150 B) 175 C) 250 D) 375

Explanation:

The given number series is 200, 200, 100, 300, 75, ?

It follows a pattern that,

200

200 x 1 = 200

200 / 2 = 100

100 x 3 = 300

300 / 4 = 75

75 x 5 = 375

Hence, the next number in the given number sequence is 375.
