Identify first the common difference of the arithmetic sequence by the following,
d = (a22 - a1) / 22 - 1
d = (-226 - 26) / 22 -1 = -12
Solving for the 31st term,
a31 = a1 + (n - 1)d
a 31 = 26 + (31 - 1)(-12)
a 31 = -334
Therefore, the answer is letter A. -334.
Answer:
10%
Step-by-step explanation:
The change is 90-100 = -10. As a percentage of the original amount, that is ...
-10/100 × 100% = -10%
The change from 100 to 90 is a reduction of 10%.
72 days and 10 weeks ( 10.2857 I just rounded)
