4. Is the following sequence arithmetic or geometric? What is the next term of the sequence? 3,6,9,12... a. Arithmetic, 15 b. Geometric, 15 C. Arithmetic, 36 d. Geometric, 36

Respuesta :

Given the sequence 3 , 6 , 9 , 12 , ......

So, the difference between the first two terms = 6 - 3 = 3

the difference between term 6 and 9 = 9 - 6 = 3

So, there is a constant common difference between the terms

which equal to 3

so, the given sequence is Arithmetic

And the next term = 12 + 3 = 15

So, the answer is a. Arithmetic, 15
