Do you mean that first D? That would be the "&" of 4 in the first measure...(the 1/8th rest before it being the "4" count)

The A would be the "1" count for the second measure, starting the count over, and the D following it would be counted as "&".

You'd count those 1/8th notes in 4/4 as "1& - 2& -3& -4&" per measure (the first note the beat number, and the 2nd note the "&")

I hope that helps, and I didn't confuse you more :)
