What do you want done? Continue the pattern?
The pattern on the bottom of the fractions:
1, 3, 9, 27, 81, 243, . . . (just keeps multiplying by 3 each time)
The next bottom would be 243 * 3 = 729
The next bottom after that would be 729 * 3 = 2187
The pattern on the top of the fractions:
-4, -2, 4, 22, 76, 238
How much is added between each pair of numbers?
2, 6, 18, 54, 162, . . . (just keeps multiplying by 3 each time.
The next step would be 162 * 3 = 486, so we would do 238 + 486 = 724
The next step after that would be 486 * 3 = 1458, so we would do 724 + 1458 = 2182
So our next two steps in the overall pattern would be 724/729 and 2182/2187
Answer: -4/1, -2/3, 4/9, 22/27, 76/81, 238/243, 724/729, 2182/2187
