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>
6 lots can be created
<em><u>Solution:</u></em>
Given that neighborhood development that is 4 acres is to be divided into
acre lots
To find: number of lots created
From given information,
Total acres = 4
one lot = 
So number of lots created can be found by dividing the total acres by acre of 1 lot
<em><u>Thus the formula is:</u></em>

<em><u>Substituting the values we get,</u></em>

Thus 6 lots can be created
