So you have the equations as well as the sequence #, so you would plug it in;
1. s(n)=4n-5 n=20
s(20)=4(20)-5
s(20)=75
C
2.s(n)=3n-2
s(16)=3(16)-2
s(16)=46
D
3. Asks for the first term n=(1) and the difference between the initial amount and the first term
s(1)=7.4+.6(1)
s(1)=8
Change of .6
D
Hope this helps!
