Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25
To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.
X - X + 25
Which gives u a difference of 25

Step-by-step explanation: Given in the question that Lana completed a 10-mile race in 90 minutes by running and walking both. She usually runs at a pace of 8.5 minutes per mile and walks at a pace of 12 minutes per mile. We need to find the number of minutes for which she ran and walk throughout the race.
Let, Lana runs for 'x' miles and walks for 'y' miles. Then, we have
Multiplying the first equation by 8.5 and subtracting from the second equation, we have
Therefore,
Thus, time for which Lana ran is
And, the time for which Lana walks is
Thus, the answers are
9 would be the right answer because -3 ^2 is 6 and 6 times 2 is 12 plus -3 is 9. so 9 is your final answer
