Answer 2

Answer:

The Missing number is 99.

Step-by-step explanation:

Hey Mate,

Lets start From Number 2

2 = 1^2 + 1

Then 3

3 = 2^2 - 1

then 10

10 = 3^2 + 1

Now missing number.

X = 10^2 - 1

=> 99

Then 9802

9802 = 99^2 + 1

The Logic behind this series is : ( Square of previous number ) + and - 1 ( by Alternative order )

So, The Missing number is 10^2 - 1  => 99
