Answer:
= 6n - 4
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
8 - 2 = 14 - 8 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 6 , thus
= 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
Thus the formula representing the sequence is
= 6n - 4
Answer:
when the survey was initially conducted the average sales of smartphones was 1.7 million units
Step-by-step explanation:
The average annual sales of smartphones is given by function
Exponential growth function is given by
Where a= initial value
b = growth factor , b= 1+r where 'r' is the growth rate
x is the time period
Now we compare f(x) with P(n)
the value of a= 1.7 that is the initial value.
So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
