Answer:
<u>-21844</u>
Step-by-step explanation:
<u>Finding n</u>
- -16384 = -4(4)ⁿ⁻¹
- 4ⁿ⁻¹ = 4096
- 4ⁿ⁻¹ = 64²
- 4ⁿ⁻¹ = (8²)²
- 4ⁿ⁻¹ = (4³)²
- n - 1 = 6
- n = 7
<u>Finding The Sum</u>
- S₇ = -4(4⁷ - 1) / 4 - 1
- S₇ = -4 (16383) / 3
- S₇ = -65536/3
- S₇ = <u>-21844</u>
Exponentiate the log or In because Exponentials are inverses of Logs and lns.
