helpppppppp
you just want to start writing out the sequence starting from n = 1, then n = 2, etc.
up to what?
since your highest answer choice is 46 you can stop when your terms start getting ~ 50 or so
(this doesn't mean n = 50, this means that your an terms should be ~50 max)
n=1 n=2 n=3 n=4 n=5 n=6 n=7 n=8
n=9 n=10 n=11 n=12 n=13 n=14 n=15 n=16
write out the an values not the n values
an = 7n + 4 start with n = 1 and tell me what an equals
like this a(1)=7(1)+4 ====11
yup, and then keep going for n = 2, then n = 3, etc.
when an gets bigger than 50, then you can stop
a(1)=7(1)+4 ====11 a(1)=7(2)+4 ====18 a(1)=7(3)+4 ====25 a(1)=7(4)+4 ====32 a(1)=7(5)+4 ====39 a(1)=7(6)+4 ====46 a(1)=7(7)+4 ====53
good. so your answer choices are 46, 36, 24, and 32. which one(s) are in your list? and which ones aren't?
46 32
good so 46 and 32 are your answers
