Solution
The correct option is A B80 The given sequence is B16, B32, B48, B64.
Here, the first letter is the same in all the terms.
We have to find the relation between the numbers.
Let us find the difference between the numbers in the terms.
Difference between the first term and the second term = 32 - 16 = 16
Difference between the second term and the third term = 48 - 32 = 16
Therefore, to find the next term in the pattern, we have to add 16 to each term.
Hence, the next number in the pattern is 64 + 16 = 80, and the next term is B80.
