Complete the following pattern, something, something, eight, seven, six, five, four, three, two, one, and zero.

In this problem, we’re given a pattern of numbers. And we’re asked to complete it by thinking of the first two numbers that happen at the start. What do the numbers sound like when we read them aloud? Eight, seven, six, five, they sound like a countdown. The sort of thing you hear when a rocket is about to take off. And that word can give us a clue as to what the pattern is doing. It’s counting down.

Let’s draw a number line to see the direction that we’re counting. The first number that we know of in our pattern is eight. And from eight, we count to seven. This is a count of one backwards. From the number seven, we also then count one backwards to get to the number six. And then, five, four, three, two, one, and zero. This is a decreasing pattern, going down by one each time.

So, what are the two numbers that come before eight? Well, we know if we’re counting backwards in ones, the number before eight is nine, nine, eight, seven, and so on. The first number in our pattern is a number that we will say before we count backwards to the number nine. The answer is 10, 10, nine, eight, and so on. And so our completed pattern is 10, nine, eight, seven, six, five, four, three, two, one, zero.
