High IQ Society Riddle #3?

Question

I created these riddles myself ..so no point Googling for these - big brain power needed here boyz... the first one is a warm up, the second one should prove tougher and the third the toughest yet. (I would post this in the Riddle section, but it seems the minds are over here)

Number 4 is fun for the kiddies - pretty simple

1. What number completes this sequence? Explain? ( 7, 7, 3, 4 )

2. is GOD a BAD IDEA ?

3. If all Plonks are Bewares are all Bewares Heeded? Explain

Fun for the kiddies:
4. What number comes next in the sequence? Explain ( 31, 91, XI, II, 21, III)

Nice Job PUZZLING - you got the Puzzle #1 and #2...

You're answer to #3 is wrong....

Riddle #2 was funny - I should post that one in the Religious forum just to see if anyone is smart enough to figure it out...

Answer 1

PROBLEM 1

The sequence is completed by a 0:
0, 7, 7, 3, 4

Now it spells HELLO upside down, instead of HELL

Or the other option is to add a 5 at the end:
7, 7, 3, 4, 5

Now it spells SHELL upside down.

PROBLEM 2

GOD = 7 + 15 + 4 = 26
BAD IDEA = 2 + 1 + 4 + 9 + 4 + 5 + 1 = 26

Using this method, it would appear that GOD does have a numeric value equivalent to BAD IDEA.

PROBLEM 3:

Regular logic doesn't say anything about whether Bewares are Heeded, so there must be something about their letters.

PLONK doesn't share any letters with BEWARE. So is this why all Plonks are Bewares? If so, then Bewares would not be Heeded, because they share the letter E.

PROBLEM 4:

Hmmm... I'll go ask my kids, hang on...

Answer 2

1. 7,7,3,4,3 because you you take everyother term and subtract so 7 -3 gives you 4, which becomes the next term. then 7-4 would be 3, then 3-3 would be 0, then 4-0 would be 4, etc.

Answer 3

4.
31, 91; XI, II; 21; III; 0
