a_38 = -5
difference d= -2.9
We use general formula

WE make the formula for a_38 th term
Plug in 38 for n

Now plug in -2.9 for d and -5 for a_38


Now add 107.3 on both sides

<h2>Number of bacteria after 6 days is 2313</h2>
Step-by-step explanation:
Population after n days is given by

Initial population, P₀ = 1000
Increase rate, r = 15 % = 0.15
Number of days, n = 6
Substituting

Number of bacteria after 6 days = 2313
2/2 is 1
You take the 1 and divide it by 4, 1/4
Your final answer is 1/4
