Q:

Find the missing number in the given number series?

625, 625, 600, ?, 475, 875

 A) 545 B) 700 C) 675 D) 725

Explanation:

Here the given number series 625, 625, 600, ?, 475, 875 follows a pattern that

625

625 + (0 x 0) = 625

625 - (5 x 5) = 625 - 25 = 600

600 + (10 x 10) = 600 + 100 = 700

700 - (15 x 15) = 700 - 225 = 475

475 + (20 x 20) = 475 + 400 = 875

Hence, the missing number in the given number series is 700.

Q:

Which fraction comes next in the sequence

 A) 1/27 B) 11/278 C) 9/48 D) 7/123

Explanation:

Clearly, the numerators of the fractions in the given sequence follow the series of 2, 3, 5, 7,... and the denominator follows 3, 9, 27, 81, 243, ...
Then, the next term in the given sequence is   .

Q:

Find the missing number in the given series ?

15, 51, 216, 1100, ?, 46452

 A) 5660 B) 6560 C) 6750 D) 6630

Explanation:

Let first no. be "k" and multiple be "l"...start value of y with 3
then,
[(k x y) + {l x (l-1)}]
Thus, we get

15 x 3 + 3 x 2 = 51
51 x 4 + 4 x 3 = 216
216 x 5 + 5 x 4 = 1100
1100 x 6 + 6 x 5 = 6630
6630 x 7 + 7 x 6 = 46452

Therefore, the missing number is 6630.

Q:

Find out the wrong term in the series 2, 5, 10, 50, 500, 5000

 A) 5000 B) 500 C) 10 D) 50

Explanation:

Each term of the series is the product of the preceding two terms
So, 5000 is wrong and it must be replaced by (500*50) = 25000

Q:

What will come in place of question mark(?) in the following number series ?

6859       5832     ?      4096     3375

 A) 4589 B) 4913 C) 5013 D) 5169

Explanation:

The given series follows a pattern that,

19 x 19 x 19 = 6859

18 x 18 x 18 = 5832

17 x 17 x 17 = 4913

16 x 16 x 16 = 4096

15 x 15 x 15 = 3375

So, the missing number in the given series = 4913
