What’s the missing number : 9876, 6447, 2527, x.?

The given pattern is 9876, 6447, 2527, x

We have to find the missing number 'x' in the given pattern.

We will use hit and trial method to get this missing number.

Let us observe the given pattern.

I have assumed the unknown number as -1884

that is the sequence becomes as

9876, 6447, 2527, -1884

Consider the difference of first term from second term that is 6447 from 9876.

6447 - 9876 = -3429

Consider the difference of second term from third term that is 2527 from 6447.

2527-6447= -3920

Consider the difference of third term from fourth term that is 2527 from -1884

= -1884-2527

= -4411

By computing the differences, we get

-3429 , -3920, -4411

Now, the difference of -3429 from -3920

= -3920-(-3429)

= - 491

Now, the difference of -3920 from -4411

= -4411-(-3920)

= - 491

Which is same.

Therefore, the missing number 'x' is -1884.
