Question

Find the missing number(s)
101, 100,?, 87, 71, 46

Answer 1

101 - 100 = 1
Sq Root Of 1 = 1.
87 - 71 = 16.
Sq. Root Of 16 = 4.
71 - 46 = 25.
Sq. Root Of 25 = 5.
Answer = 96.
96 - 87 = 9.
Sq. Root Of 9 = 3.
100 - 96 = 4.
Sq. Root Of 4 = 2.

Answer 2

Given,

A series 101, 100,?, 87, 71, 46.

To find,

?

Solution,

If we see the first and second number we find that, 101 - 100 = 1

Taking the square root of 1 = 1

If we take third and fourth number, we find that, 87 - 71 = 16

Taking the square root of 16, $\sqrt{16}=4$

If we take fourth and fifth number, we find that, 71 - 46 = 25

Taking the square root of 25, $\sqrt{25}=5$

Similarly,

Taking 100 - 96, we get 4

Square root of 4 is 2.

So, the value of ? is 2.
