Show Answer

Correct Answer :

Option B

-112

Solution :

The correct option is -112.

To find the missing term in the given number pattern, let us analyze the relationship between consecutive terms in the sequence:

-7, -28, ?, -448, -1792, -7168

We observe the pattern by finding the ratio between successive known terms:

-28-7=4

Checking the ratio for the later terms in the sequence:

-1792-448=4

-7168-1792=4

This reveals that each term in the sequence is obtained by multiplying the preceding term by 4.

Now, we can calculate the missing term by multiplying the second term (-28) by 4:

Missing term=-28×4=-112

To verify, multiplying -112 by 4 should yield the next given term (-448):

-112×4=-448

The pattern holds true throughout the sequence. Therefore, the missing term is -112.
