Identifying arithmetic sequences
SL Core 1.2
A sequence is arithmetic if the difference between consecutive terms is constant, ie un+1−un=d, the common difference, for all n. For example,
1,6,11,16…
is arithmetic, but
2,5,9,11
is not since 9−5=4=5−2=3.
General term
SL Core 1.2
The nth term in an arithmetic sequence is given by
un=u1+(n−1)d📖
where u1 is the first term and d is the common difference.
