Answer: Susie walked 4000 kilometers on day 18 of her program

Explanation:

The question explains an arithmetic progression of Susie's walk program

Now the nth term of an AP is given as

an = a1 + (n - 1 ) d

a1 =First term = 600 m

common difference , d =200

The 18th day of her program will be

a18 = 600+ (18 - 1 ) 200

a18 = 600+ 17 x200

a18 = 600+3,400

a18 = 4000
