89
Step-by-step explanation:
Answer:
= - 5.6n + 3.2
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
= u₁ + (n - 1)d
where u₁ is the first term and d the common difference
To find u₁ use the given recursive formula
u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4
from the recursive formula d = - 5.6 , then explicit formula is
= - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2
The answer is c. If you substitute k=1, 2, 3 and 4 into 2x5^k, you get 10+50+250+1250.
