To find the ring width added by each time, we need to subtract the previous amount of precipitation from the current amount of precipitation.
For the given numbers:
1.4, the difference in precipitation is 1.4 - 1.0 = 0.4
1.9, the difference in precipitation is 1.9 - 1.4 = 0.5
2.5, the difference in precipitation is 2.5 - 1.9 = 0.6
3.5, the difference in precipitation is 3.5 - 2.5 = 1.0
3.8, the difference in precipitation is 3.8 - 3.5 = 0.3
4.1, the difference in precipitation is 4.1 - 3.8 = 0.3
4.5, the difference in precipitation is 4.5 - 4.1 = 0.4
Therefore, the ring width would be added by 0.4, 0.5, 0.6, 1.0, 0.3, 0.3, 0.4 respectively.
ring width amount of precipitation If the amount of precipitation is added by 2 each ring width, what would the ring width be added by with the numbers of 1.4, 1.9, 2.5, 3.5, 3.8, 4.1 and 4.5
