Answer 2

Answer:

t_{18}-t_{13} =25

Step-by-step explanation:

Common difference of AP = d = 5

Formula of nth term in AP = a_n=a+(n-1)d

Substitute n = 18

t_{18}=t+(18-1)5

t_{18}=t+85

Substitute n = 13

t_{13}=t+(13-1)5

t_{13}=t+60

Now we are given that t_{18}-t_{13}

t_{18}-t_{13}

t+85-(t+60)

t+85-t-60

85-60

25

Hence t_{18}-t_{13} =25
