Plz help...I'll be ur fan................ Blake goes running for 10 minutes on Sunday. Every day he doubles his running time. If he continues this pattern, how many minutes will he run on the 7th day? I'm confused about which formula I should use: f(n) = f(1) • r^(n−1) or an = a1 • r^(n−1) are these even the correct formulas for this question????

yes those are the correct ones and both say the same thing if you use the second one, a1=10, r=2 and n=7

So that means that on the 7 day he would run 640 minutes???? @rajat97

day 1 =10 =10 day2 = 2*10 =20 day3 = 2*2*10 =40 ..... day7 = (2^6 )* 10 = 64*10 =640minutes @rajat97 and @plzzhelpme

this is an arithematic progression
rajat97
  • rajat97
you can use a1 + (n-1)d
rajat97
  • rajat97
here d=5, n=7and a1=50
princeharryyy
  • princeharryyy
50, 50+5, 50+5+5, 50+5+5+5, ..... and so on
