I have no idea because of the ambiguous nature of the question whether or not the next week includes 7 days or just 3 ''In preparation for the 10km mini marathon , maray starts training. she plans to run 1.5km four days this week. Each week she plans to increase the distance she runs each day by 0.5km
(i) write down the distance she plans to run in the second , 3rd and 4th week of her training programme

Hello, dcmath!

I assume she runs four days every week.

(i) Write down the distance she plans to run in the 2nd, 3rd and 4th week of her training program.

$\begin{array}{ccccccc}\text{Week 1} & 4\times 1.5 &=& 6\text{ km} \\ \text{Week 2} & 4 \times 2.0 &=& 8\text{ km} \\ \text{Week 3} & 4 \times 2.5 &=& 10\text{ km} \\ \text{Week 4} & 4 \times 3.0 &=& 12\text{ km} \\ \vdots & \vdots && \vdots \end{array}$
