Answer 1

$cn = c1 \times {q}^{n - 1} \\ c1 = 2 \\ c2 = c1 \times q = 2 \times 3 = 6 \\ c3 = c1 \times {q}^{2} = 2 \times {3}^{2} = 2 \times 9 = 18 \\ c4 = c1 \times {q}^{3} = 2 \times {3}^{3} = 2 \times 27 = 54 \\ c5 = c1 \times {q}^{4} = 2 \times {3}^{4} = 2 \times 81 = 162$
Ответ: 2, 6, 18, 54, 162
