LAMBDA for generating an arbitrary skipped list of integers

excel-lambda-EveryXtoN.txt

/*
Return every 'x' integers no larger than n, optionally skipping the first 'skip'
integers in such a sequence

e.g. 
EveryXtoN(10, 2) = {1; 3; 5; 7; 9}
EveryXtoN(10, 2, 1) = {3; 5; 7; 9}
EveryXtoN(10, 2, 2) = {5; 7; 9}

EveryXtoN(10, 3) = {1; 4; 7; 10}
EveryXtoN(10, 3, 1) = {4; 7; 10}
EveryXtoN(10, 3, 2) = {7; 10}
*/
EveryXtoN = LAMBDA(n, x, [skip], 
    SEQUENCE(CEILING.MATH((n - (x*skip)) / x), , (x*skip)+1, x)
);
