Need Bad Help With Geometry plz!!!

Here are some of the hardest questions i got today for Geometry

what are the last terms of these equations and what sequence did you use to get it? Or in other words what is the next term in each equation

1. 18, 46, 94, 63, 52, 61, __ <<<<

2. O, T, T, F, F, S, S, E, N, __ <<<<

3. 1, 4, 3, 16, 5, 36, 7, __ <<<<<<

4. 4, 8, 61, 221, 244, 884, __ <<<<<

Dont say im retarted or something for not knowing these because i have stared at these for like an hour and i do not know how to figure these out...

Your not going to convince anyone here to do your homework for you

ok im not really trying to convince im seeing if any1 offers to "help me" not do it. and it seems like you dont have a clue on how to do it hahahaha

I might help...maybe.

lmfao im in advanced and dayum this crap is hard but i figured out number 4 already

1. Answer is 90
They are backward multiples of square root integers.

9x9 = 81
8x8 = 64
7x7 = 49
6x6 = 36
5x5 = 25
4x4 = 16

2.Answer is T

They are the first letter of the numbers 1 to 10

3.Answer is 64

If I wrote it this way would it help?
1, 2², 3, 4², 5, 6², 7...

The odd terms are just the odd numbers:
1, 3, 5, 7, (9, 11, 13, etc.)

The even terms are just the (even) number squared:
4, 16, 36, (64, 100, 144, etc.)

The pattern is:
n if the term is odd, or n² if the term is even.

1, 4, 3, 16, 5, 36, 7, 64, 9, 100, 11, 144, 13, 196, 15, 256, etc.

damn man...i bet ur good at logic questions...nobody would have ever thought to try out stuff like that.
it seems so simple.
