Can someone help me solve this? I keep getting stuck
1 answer:
I can't imagine why the variable in the exponent isn't 'n'. To me, that's the only way this makes sense, and I'm going to handle it as if the exponent is (n - 1) . First term: n = 1 A(1) = -2 · 5¹⁻¹ = -2 · 5⁰ = -2 · 1 = -2 . Fourth term: n = 4 A(4) = -2 · 5⁴⁻¹ = -2 · 5³ = -2 · 125 = -250 . Eighth term: n = 8 A(8) = -2 · 5⁸⁻¹ = -2 · 5⁷ = -2 · 78,125 = -156,250 . The first choice on the list looks like the correct one.
