By Friday he would have read for 145 hours.
<u>Step-by-step explanation:</u>
Given:
Number of hours Anders read on Monday =15 minutes
Every day he increases the reading time by 7 minutes
This reading time forms an arithmetic progression
Here,
The first value is "a"=15
Common difference "d"=7
Number of days from Monday to Friday =5, Thus n=5
Number of minutes he read by Friday=sum up to 5 terms of the AP=S5
Number of times he read on Friday =a5
Thus By Friday he would have read for 145 hours.
