skip counting numbers and including the remainder

I want to skip count 1 to 100 by 4's.

So

   1:4:100

The output is until 97. I want to include the 100 in the result.

Example: 1:8:88 gives a result until 81. I want to include 88.

How do I do this? Thanks

I did not get my expected answer. I belive problem cumpsum() %Maclaurian Series for exp(0.1) n = 5; a = 0.01;

vec = [1:n]; terms = a.^vec/cumprod(vec); expVal = 1 + cumsum(terms); trueVal = exp(0.1); err = abs(trueVal - expVal);

n = 100;
step1 = 4;

seq = unique([1:step1:n,n]);
