Question 853275: Use summation notation to write the series 2.2+8.8+15.4+... for 5 terms
Note: In each of these images, the lower limit of the summation notation is either "n=1" or "n=0"
a. The answer has a 4 on top of what looks like a backwards 3, and n-0 under it and then (-5.4+6.6n)
b. 4 on top of the backwards 3 and n-0 under it and then (-4.4+6.6n) next to it.
c. 5 on top of the backwards 3 and n-1 under it and then (-6.6+4.4n) next to it.
d. 5 on top of the backwards 3 and n-1 under it and then (-4.4+6.6n) next to it.

1)
sum%286.6n-5.4%2Cn=0%2C4%29
=39
2)
sum%286.6n-4.4%2Cn=0%2C4%29
=44
3)
sum%284.4n-6.6%2Cn=1%2C5%29
=33
4)
sum%286.6n-4.4%2Cn=1%2C5%29
=77
#4 is correct
2.2+8.8+15.4+22+28.6=77
