One way to do this problem is to determine the common difference. If the 5th and 8th terms are -9 and -21, we can do this by subtracting -9 from -21:
-21-(-9) = -12. The 5th and 8th terms are not consecutive, so we have to think in terms of (8-5), or 3, times the common difference to get from -9 to -21.
Note that -12 divided by 3 is -4. Thus, the common difference is -4.
Check: -9 - 4 = -13; -13 - 4 = -17; -17 - 4 = -21 (which is correct).
We know that the 5th term is -9. To find the 4th term, work backwards: subtract (-4) from -9, which produces -9+4=-5.
The fourth term is -5. Subtracting -4 from this (which is the same as adding 4 to this -5) produces the third term; it is -1. Can you now find the 2nd and 1st terms using the same approach?
Answer:
3:5, because for every 3 ears present in the field, there are 5 legs present
Step-by-step explanation:
A cow has 2 ears and 4 legs.
20 cows have 40 ears and 80 legs.
A farmer has 2 ears and 2 legs.
10 farmers have 20 ears and 20 legs.
20 cows and 10 farmers have 60 ears and 100 legs.
Ratio of ears to legs is
60:100 = 3:5
Answer: 3:5, because for every 3 ears present in the field, there are 5 legs present
