Answer: What Comes Next? #415

The answer is D: 3.

The rule

Halve the number each time (divide by 2). In Python, // divides and gives a whole number.

The pattern as Python code

Here is a tiny Python program that follows the same rule. Type it into IDLE and run it to print the whole pattern, including the answer.

number = 192
for step in range(7):
    print(number)
    number = number // 2

When you run it, Python prints:

192
96
48
24
12
6
3
