Answer:

A13=0

Option (a)

Step-by-step explanation:

5th term

An=a+(n-1)d

A5=a+(5-1)d

A5=a+4d

8th term

An=a+(n-1)d

A8=a+(8-1)d

A8=a+7d

5(A5)=8(A8)

5(a+4d)=8(a+7d)

5a+20d=8a+56d

5a-8a=56d-20d

(-3a)=36d

(-3a)-36d=0

3a+36d=0

3(a+12d)=0

a+12d=0

13th term

An=a+(n-1)d

A13=a+(13-1)d

A13=a+12d

A13=0(a+12d=0)
