It is an ordered set of numbers such that the difference between adjacent numbers is a constant.
Contour numbers.
{1, 2}, {7, 8} and {10, 11}. The triangular numbers are 1, 3, 6, 10, 15, 21, 28, ... The sum of two adjacent numbers is odd, so adjacent numbers that sum to 1, 3, 15, 21 are the solution. 1 is impossible, leaving 3, 15 & 21 as possible sums, giving the adjacent numbers {1, 2}, {7, 8} & {10, 11}

There are 2941 4-digit numbers such no two of its digits differ by 1.
No, because every other even number besides 2 is composite and odd numbers are never adjacent.
Because if two numbers are adjacent, then one of them is odd and one is even. But ' 2 ' is the only even prime number there is.
If you add together any two adjacent numbers from 1 to 30, the result will always be odd only if one number is odd and the other is even. However, in the sequence from 1 to 30, adjacent pairs consist of either two odd numbers or two even numbers, both of which yield even sums. Therefore, it is impossible to achieve a situation where the sum of any two adjacent numbers is odd in this case.
No, the two adjacent square numbers are 10^2 or 100 and 11^2 or 121
