Explanation:
To find the daily length of the creeper, we can create a table:
Day | Length (cm)
-----------------
1 | 15
2 | 30
3 | 60
4 | 120
5 | 240
6 | 480
7 | 960
From the table, we observe that the length of the creeper doubles each day. This suggests an exponential relationship between the number of days and the length of the creeper.
The pattern rule for this situation can be expressed as follows:
Length of creeper = 15 × 2^(number of days - 1)
So, in the case of observing on the 7th day, we have:
Length of creeper = 15 × 2^(7 - 1) = 15 × 2^6 = 15 × 64 = 960 cm.
