9=90
8=72
7=56
6=72
3=?

Answers
Answer:
The value corresponds to 3 in this pattern =12
Step-by-step explanation:
Given
9 = 90
8 = 72
7 = 56
6 = 72
To find
The value of 3
Solution:
9 = 90 = 9×10 = 9(9+1)
8 = 72 = 8 ×9 = 8(8+1)
7 = 56 = 7 ×8 = 7(7+1)
6 = 42 = 6 ×7 = 6(6+1)
------------------------------
Following this pattern we can conclude that
n = n(n+1) -----------------------------(1)
To find the value 3, substitute the value of 'n' as 3
3 = 3(3+1) = 3×4 = 12
The value corresponds to 3 in this pattern =12

Correct Question :
If 9 = 90 , 8 = 72 , 7 = 56 , 6 = 42 then find 3 = ?
Answer:
If 9 = 90 , 8 = 72 , 7 = 56 , 6 = 42 then 3 = 18
Step-by-step explanation:
Given :
we are given some relations
9 = 90 , 8 = 72 , 7 = 56 , 6 = 42
To Find :
The value of 3 = ?
Solution :
Since given relations are
9 = 90 , 8 = 72 , 7 = 56 , 6 = 42
observing the relations we get that
9 x 10 = 90
8 x 9 = 72
7 x 8 = 56
6 x 7 = 42
we can clearly observe that the next relation will can be get by multiplying 3 to 6
then
3 x 6 = 18
Hence we have calculated the value of 3 = 18
