Question

The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?
A.) 14/13
B.) 25/7
C.) 4

Answer 1

Answer:

C

Step-by-step explanation:

the 15th term = a + 14d

it means a + 14d = 53

               -3 + 14d = 53

                        14d = 56

                           d = 4
