Question

The first term of an arithmetic sequence is 3. The common difference of the sequence is 1.5 times the first term. Write the next three terms of the sequence. Then graph the sequence. Also explain how you got the answer if possible​

Answer 1

Answer:

Step-by-step explanation:

Tn = a + (n-1)d

a = 3 and d = 1.5×3 = 4.5

T2 = a + d = 3 + 4.5 = 7.5

T3 = a + 2d = 3 + 2(4.5) = 12

T4 = a + 3d = 3 + 3(4.5) = 16.5
