The Fibonacci sequence starts with the numbers 0,1,1,2,3,5,8 what are the next 3 terms in the sequence
shutvik [7]

It has been given that the Fibonacci sequence starts as 0, 1 , 1 , 2 , 3 , 5 , 8

We can see that every term is equal to the sum of the previous two terms

We already have 7 terms, so to determine the next three terms:

term 8 = t₈ = t₇ + t₆ = 8 + 5 = 13

term 9 = t₉ = t₈ + t₇ = 13 + 8 = 21

term 9 = t₁₀ = t₉ + t₈ = 21 + 13 = 34

Hence, the next three terms are 13, 21 and 34. So the correct option is B

If y = 8(2. 4)* represents the number of bacteria in a culture at time t, how
andriy [413]

Answer:

21134 bacteria

Step-by-step explanation:

The given parametrs can be interpreted as:

y = 8(2.4)^t

Required

Find y when t = 9

Substitute t = 9

So:

y = 8(2.4)^9

y = 8 * 2.4^9

y = 8 * 2641.81

y = 21134.48

y = 21134 --- approximated

<em>Hence, there are 21134 bacteria</em>
