How can I create a for loop that takes the number 500 and multiplies it by 1.1 every 7 steps (7,14,21,...), meaning that i want the answer as follows: 500.... 500*1.1...​.500*1.1*1​.1....500*​1.1*1.1*1.​1 etc

Here's a start

a = 500;
k = 1.1;
p = 0:5;
s = 7;

x = a*k.^p;
x = repelem(x,s)

just adjust p as needed to get the desired length.

It says "Undefined function 'repelem' for input arguments of type 'double'"

repelem() has been builtin since R2015a, so I guess you're running an older version. You can do the same thing without it.

x = reshape(repmat(x,[s 1]),[],1).'

Plus, she asked specifically for a "for loop" though I'm not sure that is mandatory.

[DGM]

I'm beginning to take "how can i make a for loop to do x" questions as simply "how can i do x? i'm thinking of using a bunch of loops, please stop me". OP is free to clarify that loops are necessary.

[May Kh]

The for loop is not mandatory... But for the problem I have I should do this for 210 years every 7 years... And the answer I get from each 7 should be added together for the purpose of my question.. I haven't been specific with the question itself since it has lots of equations and calculations to do... The for loop would serve the best at what I'm trying to do :)
