Answer:
use the formula sn= n(a1+an)/2
Step-by-step explanation:
2982=28(228+an)/2
5964=28(228+an)
5964/28=228+an
213=228+an
an=-15(last term)
to find difference use formula
an = a+(n-1)d
-15=228+(28-1)d
-243=27d
d=-243/27
d=-9
arithmetic sequence can be found be keep on subtracting 9 from 228
hence the arithmetic sequence is
228, 219, 210, 201, 192, 183, 174........-15

Answer:
74.4°F?
Step-by-step explanation:
It started at 65°F and they recorded the change. So 65 + 2.5 = 67.5 - 1.7 = 65.8 + 5.5 = 71.3 + 3.1 + 74.4? I think that is how it is solved. I could be wrong... it's been a while haha
^^That is finding the full temp. overall. If you are looking for the change, it is 9.4
