Dear all my team members
How is your day? I got a new present for you, a lecture note as usual.
A sequence such as 1, 5, 9, 13, 17 or 12, 7, 2, –3, –8, –13, –18 which has a constant difference between terms.
Can you find the nth term of the sequence?
But I will give you another one that looks much easier.
