Ok so i have a function to write and it is supposed to calculate and return the product of 1 to n in a step size of 2.
for n = 1:2
inv(1*3*5*7);
end
How do i make this a step size of two? Do i do for n = 1:n:2?

You’re getting there.
From the documentation:
Using two colons to create a vector with arbitrary real increments between the elements,
E = 0:.1:.5
results in
E =
0 0.1000 0.2000 0.3000 0.4000 0.5000

Hi Tony,
Either type help for in the MATLAB command window to get information on for loop syntax, or visit the following link: for loop.

No for loop is needed at all. See the prod() function.
And you got the colon stuff in the wrong order. The correct order is startingValue : stepAmount : endingValue. You put the step at the end instead of the middle.

Anyway, that problem is trivial, toddler-level stuff. Here's a far more interesting question for you:
Investigate these two different equations with different values of n:
sum1 = 1^n + 19^n + 20^n + 51^n + 57^n + 80^n + 82^n
sum2 = 2^n + 12^n + 31^n + 40^n + 69^n + 71^n + 85^n
Explain what you see and why you see it.
