Answer:Green
Step-by-step explanation:
2z^7
-3--5=2. z^7
Since both have the same exponent
2y-2>-4+2. Add 2 to both sides. Now you have 2y>-2+2. Erm. I might be wrong since I JUST learned this unit and I made some mistakes. Ok soo, add 2 to both sides again. Now you have 2y+2>2. Subtract 2 from both sides. You now have 2y>0. You have no solution since 2 can't be divided by 0. I'm probably wrong but I hope I helped...ish.
Answer:

Step-by-step explanation:
a₁ = 1 - 5(1 - 1) = 1 - 5·0 = 1
a₂ = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a₁ - 5
a₃ = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a₂ - 5
a₄ = 1 - 5(4 - 1) = 1 - 5·3 = 1 - 5 - 5 - 5 = a₃ - 5
and so on, therefore:
<h3>
aₙ = aₙ₋₁ - 5</h3>
