You have to calculate to see how many sts you need to decrease.
So you subtract 69 from 94 and get 25 sts. This tell you that you need to decrease 25 sts total.
Now we have to figure out how to space them out evenly. So we have to divide 94 by 25 and get roughly 3.7 which is a bad numbers for us.
In this situation I would do decrease every 3rd and 4th st alternately. This is the best we can do, I think.
Here is what you do;
Work 4 st, k2tog, *(k2, k2tog, k1, k2tog) repeat * to last 5 sts. It should be something like that.
