Sorry for the delay but I answered your question and the answer is -6xsquare +11x-4
Answer:
Correct choice is B
Step-by-step explanation:
For the numbers -1 and 59, find the difference 59-(-1):
since 59-(-1)=60 and (two arithmetic means tells you there will be three intervals), two arithmetic means will be
- -1+20=19;
- 19+20=39.
The only correct sequence is -1, 19, 39, 59.
