Question

IF 2=11, 3=30,4=67,5=128 THEN 1=?

Answer 1

its answer is 1=4 because

2=2cube+3

2=8+3

2=11  

similarly , 3=30

4=67

Answer 2

We have:

2 = 11, 3 = 30, 4 = 67, 5 = 128

We have to find, the value of 1 = ?

Solution:

The pattern follow:

$(Number)^{3}$ + 3.

11 = $2^{3}$ + 3

= 8 + 3 = 11

30 = $3^{3}$ + 3

= 27 + 3 = 30

67 = $4^{3}$ + 3

= 64 + 3 = 64

128 = $5^{3}$ + 3

= 125 + 3 = 128

Similarly,

? = $1^{3}$ + 3

= 1 + 3 = 4

∴ Missing number (?) = 4

Thus, if 2 = 11, 3 = 30, 4 = 67, 5 = 128, then "1 = 4".
