1.6.13 Standard formulae for arithmetic series (A-level only)

In an arithmetic sequence, consecutive terms have a [     ], represented by ddd.

A

The nth term of an arithmetic sequence is un=a+(n−1)d\boxed{u_n=a+(n-1)d}un​=a+(n−1)d​.

B

n=16n=16n=16; reject the negative root −352-\frac{35}{2}−235​.

C

In an arithmetic sequence, consecutive terms have a constant difference, represented by ddd.

D

SnS_nSn​
