Greetings, Mister Low. You are correct for the answer in part b. I made a careless mistake.
The way I see the pattern is the total number of squares being the pattern number multiplied by the next higher integer.
The number of white squares is the pattern number multiplied by the order of the pattern number as an odd or even number. So 15 is the 8th odd number, so we have 15 x 8 = 120.
In even rows, the white and grey squares simply share the total number of squares evenly.

Yes my working probably makes more sense to secondary school students, while yours solves it in a way that is much simpler and easier to understand, and this is probably what the question is expecting. Thanks
Thank you, Mister Low. I love your explanation for the question. Regards
