Question 13
13.
You'll need to create a mini sequence from row 8 to 20...use it to find the 'd'...then create another mini sequence from row 20 to row 80 to get the final answer.
This would be considered a tough one...would be worth more than others...but technically, if you can find the 'd', you could walk your way up to the 80th term.
