ORDERED PAIRS
5, 4, 3 (an old one in disguise)
The ordered pair is formed in the following manner:
(next integer, number of letters in the spelling of that integer)
e.g., eight has 5 letters in its name; hence, (8,5)
Well spotted, they are all ?'old' in one way or another.
MOOD to BARN
moon - boon - born (these are fairly easy when the number of steps equals the number of letters that have to change)
The easy ones are for ?'newbie's'
FOUR DISTINCT INTEGERS
386, 2114, 3970, 10430
These numbers satisfy the conditions below.
386+2114=2500=50^2
386+3970=4356=66^2
386+10430=10816=104^2
2114+3970=6084=78^2
2114+10430=12544=112^2
3970+10430=14400=120^2
386+2114+3970+10430=16900=130^2
Sketch of a non-brute-force solution:
The sum of all four (a+b+c+d) is the square of the right-hand side of a Pythagorean triple in three different ways, so it has to be divisible by a handful of prime factors, each of which is 1 mod 4 (or else the prime 2). Since it cannot exceed sqrt(4*12000) < 220, there are not that many candidates. The right one turns out to be 130=2*5*13.

"Here's one to play with while waiting for the Super Bowl to start."
It started, finished, the night came and went. Morning brought a answer.
