that's the whole question just don't know which answer it is

anonymous · Answer

The first term is f(1), that's 10. 
f(n + 1) = f(n) – 2 means you subtract 2 to get the next term

phi · Answer

f(n + 1) = f(n) – 2 for f(1) = 10

try to learn how to interpret  this
First,  f(1)  is short for "the first term"  (that is what the 1 in f(1) means)
so the first term in your answer should be a 10

phi · Answer

Can you learn that 
f(1) = some number
that will be the first number in a list?
