Here is the puzzle as it appeared in the AARP Magazine:

1	+	2	+	3	=	X
4	+	5	+	6	=	N

Here are some additional clues from Mr. P:

1	+	4	+	7	=	E
2	+	5	+	8	=	N
3	+	6	+	9	=	N

Solution:

The answer is the letter R.   It is the last letter of the sum (TWENTY-FOUR).

1 + 2 + 3 = SIX
4 + 5 + 6 = FIFTEEN

2 + 5 + 8 = FIFTEEN
3 + 6 + 9 = EIGHTEEN
