Match each verbal description of a sequence with its appropriate explicit function. an=4+ 2(n-1) an = 3. (4)-1 an=4-(239-1 an = 2 + 3(n - 1) an = 3 + 4(n-1) an = 2 · (3)n - 1 a geometric sequence with first term of 3 and a common ratio of 4 an arithmetic sequence with a first term of 3 and a common difference of 41 - a geometric sequence with first term of 4 and a common ratio of 2 an arithmetic sequence with a first term of 2 and a common difference of 3 -
