Card 1 of 22
In a model, how does a sequence differ from a series?
A
un+1=0.6un+30u_{n+1}=0.6u_n+30un+1=0.6un+30
B
A geometric sequence.
C
For an arithmetic sequence, the nnnth term is un=a+(n−1)d\boxed{u_n=a+(n-1)d}un=a+(n−1)d.
D
- A sequence gives the value at each stage.
- A series gives an accumulated total.
