To identify the number pattern and complete it, we can start by examining the given numbers: 12980, 12970.
The difference between the first two numbers is:
12980 - 12970 = 10.
This indicates that the pattern appears to involve subtracting 10 from each successive number.
Therefore, to continue the pattern:
- 12970 - 10 = 12960
- 12960 - 10 = 12950
- 12950 - 10 = 12940
So, the completed sequence is:
12980, 12970, 12960, 12950, 12940.
Rule: Subtract 10 from the previous number to find the next number in the sequence.
