Arithmetic sequence yan.  Ang equation ay
      an = a1 + (n-1) (d)
   
kung saan ang
                            an = value ng pinakahuling numero sa sequence na given o value ng hinahanap na term
                            a1 = yung una sa hanay ng sequence
                            n = kung ilan o pang ilan ang sequence (nth term)
                            d = difference o yung sagot if you subtract ang kahit alin sa dalawang magkasunod na sequence

Halimbawa, multiple of 4, ang sequence ay:

4, 8, 12, 16, 20, 24

an = 4 + (n-1) (4)
an = 4 + 4n - 4
an = 4n   equation para sa multiples of 4

multiples of 5
5, 10, 15, 20, 25, ...
an = 5 + (n-1) (5)
an = 5 + 5n - 5
an = 5n

multiples of 6:
6, 12, 18, 24, 30, ...

an = 6 + (n-1) (6)
an = 6 + 6n - 6
an = 6n
