Answer:

aₙ = a₁ - 6* (n-1)

Step-by-step explanation:

a₁ = 13 = 13 - 6* (1-1)

a₂ = 7 = 13 - 6 * 1 = 13- 6*(2-1)

a₃ = 1 = 7 - 1 = 13 - 6 * 2 = 13 - 6 * (3-1)

........

aₙ = a₁ - 6* (n-1)

check: a₅ = 13 - 6*4 = -11

Mrs. Lay's Instagram followers went from<br> 40 to 72. What was the percent increase?
anastassius [24]

<u>Answer:  </u>

The percentage increase when Mrs.Lay’s instagram followers went from 40 to 72 is 80%

<u>Solution:</u>

The percentage increase can be found out by dividing change in value by initial value. This is given as,

\bold{\text { percentage increase } = \frac{( \text {final count-initial count} }{\text {initial count}} \times 100}

From question, we get

Initial count of Mrs.Lay = 40

Final value of Mrs.Lay = 72

So percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is

\text { percentage increase }=\frac{72-40}{40} \times 100= \frac{32}{40} \times 100

=\frac{4}{5} \times 100

= 80  

Hence percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is 80%.
