Answer:
Step-by-step explanation:
Here we have the first term but must find the common ratio, r.
The nth term is a(n) = 8(r)^(n - 1).
To find r, substitute 9 for n in the above, obtaining 8(r)^(9-1), or
a(9) = 8(r)^8 = 56.
Solving for r^8, we get 56/8, or just 7.
Then r^8 = 7, and so r = 7^(1/8).
Thus, a(n) = 8(7)^(1/8)^(n-1), and so
a(24) = 8(7)^(23/8), or 2151.53
If you calculate 20-3.58 the answer is $16.42
Answer:
x > -2
Step-by-step explanation:
to get 4x alone, we have to subtract 3 from -5
-5 - 3 = -8
4x> -8
-8/4 = -2
x>-2
Answer:
= 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
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 = 7 and d = 4, thus
= 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
