Answer 2

Answer:

Number Series: 0, 12, 18, 80, 111

Step-by-step explanation:

The Series provided: 0, 12, 18, 80,..

Interval of 0, 12 = 12

Interval of 12, 18 = 6

So, In the first three numbers;

Interval of first two = 2 × (Interval of last two)

i.e; 12 = 2 × (6)

Simillary: Interval of 18, 80 = 80 - 18 = 62

Let the missing number (?) is x

Interval of 80, x = x - 80

Now,

$Interval \: of \: 80, x \: = x - 80 \\ = \frac{1}{2} (interval \: of \: 18 \: 80) \\ = \frac{1}{2} \times 62 \\ = 31$

So we get,

$x - 80 = 31 \\ or \: x = 80 + 31 \\ x = 111$

So the missing number is 111
