Me too.
My method was something like that:

119-6=113
113x8=904
904+49=953

I tried and tested this method with the given patterns before using it as my final answer

It just asks to write the number. No need write units.
I wrote 12 too.

so she says only wrong for p2 q17 (c), she get 827. the rest all correct.

I am not sure if this can be understood without the pattern, but this is how I worked it out:


I found Pattern 120 like this:

(120-2)/2x13+20= 787

Then,
to find Pattern 119, just minus 5, which gives 782
