The first term of an arithmetic sequence is 3. The common difference of the sequence is 1.5 tune the first term. Write the next five terms in the sequence:

3, 7.5, 12, 16.5  

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

Hope its correct and have a great day :)
