Look at this part of a calendar month. In one column (same weekday) the dates are 7 apart: 3, 10, 17, 24, 31. If a date d falls on a Tuesday, which expression gives the date of the Tuesday three weeks later (in the same month, if it exists)?

Question

Accepted Answer

d + 21. Each week later adds 7 days; three weeks later adds 3 x 7 = 21. So the date is d + 21.
