LCM(18, 54, 81) = 162
162, 486, 1458
The factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162.
To find the common ration in a geometric sequence, divide one term by its preceding term: r = -18 ÷ 6 = -3 r = 54 ÷ -18 = -3 r = -162 ÷ 54 = -3
6 is.
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
162 and 486 the pattern is that the next number is three times the previous number.
The pattern looks like the previous number is multiplied by -3, hence the next number in the sequence would be (-54) x (-3) = 162
