16 bc one side is 5ft so the other must be 3 to have an area of 15. Then 5+5+3+3= 16ft
Option A is correct answer
Answer:
A.
<u>The first 5 terms:</u>
- a₁ = (2*1 + 3) / 4 = 5/4
- a₂ = (2*2 + 3) / 4 = 7/4
- a₃ = (2*3 + 3)/ 4 = 9/4
- a₄ = (2*4 + 3) / 4 = 11/4
- a₅ = (2*5 + 3) / 4 = 13/4
B.
<u>The first 5 terms:</u>
- a₁ = (1 - 3) / (1 - 2) = 2
- a₂ = (2 - 3) / (2 - 2) = undefined
- a₃ = (3 - 3)/ (3 - 2) = 0
- a₄ = (4 - 3) / (4 - 2) = 1 / 2
- a₅ = (5 - 3) / (5 - 2) = 2 / 3
