Emek, Luna, and Pixel followed a dusty safari trail to the elephant camp. They saw signs at 5, 10, and 15 steps. Emek noticed that each sign came 5 steps after the last one. Luna predicted the next signs would be at 20, 25, and 30 steps. Pixel checked the pattern as they walked. At 30 steps, they found the final sign pointing straight to the elephant camp.

Challenge 1 of 5
Challenges
Challenge 1 of 4
Hint
Look at how much the number changes from one sign to the next.
The safari signs follow the pattern 5, 10, 15, 20. Which rule describes the pattern?
Add 2 each timeAdd 5 each timeAdd 10 each timeTake away 5 each timeCorrect! Each sign is 5 steps after the one before it.
Try again. Compare 5 to 10 and 10 to 15.
Next🎉 Congrats! You got this question!
Hint
Start at 15 and count forward by 5.
Pixel sees signs at 15 steps and 25 steps. There should be one sign between them if the pattern keeps adding 5. At how many steps should that sign be?
Correct! The missing sign should be at 20 steps.
Try again. Add 5 to 15 to find the sign between 15 and 25.
Next🎉 Congrats! You got this question!
Hint
The signs keep appearing every 5 steps.
Suppose there were one more sign after the final sign at 30 steps. If the same pattern continued, which pair would show the final sign and the new sign?
30, 3130, 3230, 4030, 35Correct! Five more than 30 is 35.
Try again. Continue the same counting-by-5s pattern after 30.
