Each term is 3 times greater than the previous term and so the next term will be 486
6, 2, ⅔
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.
18
The pattern looks like the previous number is multiplied by -3, hence the next number in the sequence would be (-54) x (-3) = 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, 2, ⅔
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.
Convert the percentage to a decimal:18% = 18 / 100 = 0.18Next . . .What is 18% of 162= 18% * 162 = 0.18 * 162 = 29.16
162 ÷ 18 = 9.
162 486 1458 4734 and so on just multiply number by 3
This is an arithmetic sequence with t1 = 1 and the common difference d = -18.The nth term of an arithmetic sequence is given by the formula:tn = t1 + (n - 1)d (substitute 10 for n, 1 for t1, and -18 for d)t10 = 1 + (10 - 1)(-18) = 1 + 9(-18) = 1 - 162 = -161Thus the 10th number of the sequence is -161.
The LCM is 162.
