Chanel Day · Answer 1

Step-by-step explanation:

General Remark

Let's start with the long way.

Each day 1 traditional candle (shamash) is lit along with a number of candles representing that day of Chanukah. I'm taking it that a new Shamash candle must be used each day.

Total Candles = 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 44

Givens

a = 2 L = 9 n = 8

Formula

Sum = (a + L) * n/2

Solution

Sum = (2 + 9) * 8/2 Sum = (11) * 4 Sum = 44

If this is wrong can you tell me what assumption I'm making that is incorrect.
