The answer provides a step-by-step calculation of the total number of washing machines that arrived in the first 6 months based on a tripled sequence.
To find the total number of washing machines that arrived over the first 6 months, we can set up a sequence where each month the number of washers triples. If 12 washers arrived in the first month, the sequence would be: 12, 12 x 3 = 36, 36 x 3 = 108, 108 x 3 = 324, 324 x 3 = 972, 972 x 3 = 2916. To find the total for the first 6 months, add all these numbers together: 12 + 36 + 108 + 324 + 972 + 2916 = 4368. Therefore, a total of 4,368 washing machines arrived in the first 6 months.
