Question

7=42
6=30
5=20
3=?
Can you solve

Answer 1

Answer:

If 9=72, 8=56, 7=42, 6=30, 5=20, then what will 3 =?

6

Step 1 : 9=72 & 8=56

So, in 8 & 9, values are 72 & 56 resp. The gap between the two are

72 - 56 = 16

Step 2 : 8 = 56 & 7 = 42

So, in 8 & 7, values are 56 & 42 resp. The gap between the two are

56 - 42 = 14

Step 3 : 7 = 42 & 6 = 30

So, in 7 & 6, values are 42 & 30 resp. The gap between the two are

42 - 30 = 12

Step 4 : 6 = 30 & 5 = 20

So, in 6 & 5, values are 30 & 20 resp. The gap between the two are

30 - 20 = 10

Step 5 :

From steps 1, 2, 3 & 4 its’s clear that the gap between the next sequence is 8.

4 = x

So, now

20 - x = 8

X = 20 – 8

X = 4

So, 4 = 12

Now, to find 3 = y, we know that the gap between the next sequence is 6.

So, now

12 - y = 6

Y = 12 – 6

Y = 6

So, 3=

Answer 2

Answer:

The answer is 6

Step-by-step explanation:

7*(7-1)=42

3*(3-1)=6
