The first four terms of a sequence are shown below:

8, 5, 2, -1

Which of the following functions best defines this sequence?
f(1) = 8, f(n + 1) = f(n) + 3; for n ≥ 1
f(1) = 8, f(n + 1) = f(n) - 5; for n ≥ 1
f(1) = 8, f(n + 1) = f(n) + 5; for n ≥ 1
f(1) = 8, f(n + 1) = f(n) - 3; for n ≥ 1

hartnn · Answer

so 1st term = 8 
means f(1) = 8

hartnn · Answer

now do u see any pattern in your sequence?

hartnn · Answer

like adding/subtracting a number from the current term, gives you next term?

anonymous · Answer

a

hartnn · Answer

umm..i asked about the pattern ...
not about what you think could be the answer :)

anonymous · Answer

some thing minus or add 5

hartnn · Answer

5? are you sure?
