Penjelasan dengan langkah-langkah:

Nomor 2 :

[tex]un = {n}^{2} \\ u14 = {14}^{2} \\ = 14 \times 14 \\ = 196[/tex]

Nomor 3 :

[tex]un = n(n + 1) \\ u30 = 30(30 + 1) \\ = 30(31) \\ = 930[/tex]

Nomor 4 :

[tex]un = \frac{1}{2} n(n + 1) \\ u40 = \frac{1}{2} .40(40 + 1) \\ = \frac{40}{2} (41) \\ = 20 \times 41 \\ = 820[/tex]
