What letter should appear next in this sequense? A I M O ?

[mallyh]

Q they are mirror images ?

[mallyh]

mirrored images

[barmy]

If there mirror images, then T would be next.

[Baldric]

L ?

[sunny-dave]

P?

The numerical sequence is 1 9 13 15 so the gaps are 8 4 2 so a gap of 1 gives 16 which is P

[mallyh]

yes your right about t, i forgot the little tail on the Q

[Jomlett]

P?

[Sipowicz]

Why the L not! ;-)

[aelmpvw]

T

[sunny-dave]

(H is missing from the mirrored series)

[auntflo]

I was going to say T as they all have a vertical line of symmetry, but then H should be in the list, so it can't be that.
A bit tenuous but, P? A-I is 8 letters, I-M is 4, M-O is 2, O-P is 1????

[auntflo]

sorry sunny-dave, your post wasn't there when I started typing!

[aelmpvw]

P it is

[mallyh]

do you know the answerDavidHulme?

[DavidHulme]

Thank you for the reason so it must be T for the tail on the Q would be on the wrong side

[chelle7272]

No I think auntflo and dave have it right - the H would be included if they were mirror images as has been said
