So I have question where the first term is 28 and increases by 3 for every term afterwards. There is a known total of 17000, how many terms until we get to that total. Please help
Have you substituted in a = 28, d = 3 and sum = 17 000 - your photo only shows the formula

HOWEVER, unless I made a slip, there is an error in the question. You cannot get a total of 17000 exactly. Please check the original question. I suspect it should say 170.
