If they're asking for the nth term, you should use n in your formula, ie.,

a(n) = 6000 * 0.5ⁿ

However, the first term is when n=1, so your formula should really be:

a(n) = 6000 * 0.5⁽ⁿ⁻¹⁾

Then the 8th term is 46.875

I really need some help on this question soo any answer would be helpful ∧_∧
lidiya [134]
Ok this one is a little bit more tricky since there are more possible answers. But we can do it! So look at the y-intercept. It lands on 25. Now we do "Rise over Run". So we go up 4 and left 1. Since the line is going left, the slope is a negative. And the line is solid instead of dotted so it is , ≤. Your answer would be the first option. I hope this helps love! :)
