Question 60

The Sétimo family — Mr. and Mrs. Sétimo have 7 children, all born on April 1, on six consecutive occurrences of that date. This year, for their birthdays, Mrs. Sétimo made one cake for each child, with as many candles as that child's age in years. João Sétimo, the son who likes mathematics most, noticed that this year's total number of candles is twice the total 2 years ago, and that there are 2 more cakes. How many candles will be lit this year?
