Answer:

-53 (answer : B)

Step-by-step explanation:

hello :

this the arithmetic sequence because :

(-9)-(-13)=(-13)-(-17)= 4  (common difference)

the first term is : A1 = -17

the nth term of an arithmetic sequence is :

An= A1 +(n-1)d   ....a common difference is : d

the 10th term is : A10

A10= -17 +(10-1)(4) = -17-36 = -53 (answer : B)
