What are the next three numbers? 300, 350, 400, what, what, and what.
This is a sequence of six numbers, but we’re only given the first three, 300, 350, and then 400. And we’re asked to give the next three numbers. But in order for us to be able to do this, we need to work out what the rule is for our sequence. We can see that this is an increasing pattern. The numbers are getting larger as we read them from left to right. So we can predict that the rule might be something to do with addition.
To get from 300 to 350, we add 50. And the same is true as we go from 350 to 400. If we look at these numbers, we’re skip counting in 50s, 300, 350, 400. So let’s carry on skip counting in 50s to find our remaining three numbers. We’ll start with 400, 450, 500, 550. Counting in 50s is one of those patterns that we can actually hear as we listen to the numbers, 300, 350, 400, 450, 500, 550.
We recognized that this pattern was counting on from a number in 50s. So to find our answer, we had to count on from the last number we were given, which was 400, in 50s. The next three numbers in the sequence are 450, 500, and then 550.
