5 6 ?
2 3 8
33 10 33

Answer 1

Answer:

? = 13

Step-by-step explanation:

7   3   4

5   6   ?

2   3   8

33  10 33

7

5

2

33

=> (7 - 1) * ( 5 + 1)  - (2 + 1)  = 6 * 6 - 3 = 36-3 = 33

3

6

3

10

=>(3 -1 ) * (6 + 1) - (3 + 1) = 2 * 7 - 4 = 14 - 4 = 10

4

?

8

33

=> (4 - 1) * ( ? + 1)  - (8 + 1) = 33

=> 3 *  ( ? + 1)  = 42

=> ( ? + 1)  = 14

=> ? = 13

rule is

a

b

c

d

=> (a - 1) * (b + 1)  - (c + 1) = d

Answer 2

Answer:

The required number is 13.

Step-by-step explanation:

Consider the provided series.

Observe the first column.

$(7-1)(5+1)-(2+1)=6\times6-3=33$

Now observe the second column.

$(3-1)(6+1)-(3+1) = 2\times7-4=10$

By following the same pattern.

$(4-1)(?+1)-(8+1)=33$

$3(?+1)=33+9$

$3(?+1)=42$

$?+1=14$

$? = 13$

Hence, the required number is 13.
