Lloyd is to start training in order to run a marathon.

For the first week of training he will run a total of 2 miles.

Each subsequent week he’ll increase the total number of miles run by 3 miles.

He intends training for 15 weeks.

Calculate how far Lloyd will run during his eighth week of training

Work out how much further Lloyd will run in his last week of training compared to his first.

Find the total number of miles Lloyd will run across all 15 weeks of his training schedule.
