Answer:
-53 (answer : B)
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)
