Question

the comman diff of AAp is 5 then a10-a6 is​

Answer 1

Step-by-step explanation:

ANSWER

Given, common difference of the AP,

d=5

We know that,

an=a1+(n−1)d

Then, 

a18=a1+17×d

a13=a1+12×d

Solving the two equations, 

a18−a13=a1+17d−a1−12d

a18−a13=5d,

Substituting d=5,

a18−a13=25
