Oblicz sześć początkowych wyrazów ciągu (an), jeśli:
an = 1/3 n dla n E {3,6,9,12,...}
an= n2+1 dla n E (<---to E jest przekreślone) {3,6,9,12,...}

an = 1/3 n dla n E {3,6,9,12,...}
1.
a3 = 1/3 * 3 = 1
2.
a6 = 1/3 * 6 = 2
3.
a9 = 1/3 * 9 = 3
4.
a12 = 1/3 * 12 = 4
5.
a15 = 11/3 * 15 = 5
6.
a18 = 1/3 * 18 = 6
an= n2+1 dla n E (<---to E jest przekreślone) {3,6,9,12,...}
a1 = 1² + 1 = 1 + 1 = 2
a2 = 2² + 1 = 4 + 1 = 5
a4 = 4² + 1 = 16 + 1 = 17
a5 = 5² + 1 = 25 + 1 = 26
a7 = 7² + 1 = 49 + 1 = 50
a8 = 8² + 1 = 64 + 1 = 65
