Maths help please!Watch
I'm slightly stuck with this question and I'm struggling to see how to begin please can someone help?
Thanks in advance
Un = a + (n-1)d so, 25,000 + (n-1)1000
Un = ar^n-1 so, 22,000*1.05^n-1 ?? Why have you used 1.05 by the way?
Your setup should be this:
Can you take it from there?
