Best ResponseYou've already chosen the best response.0Well first you have to find the common ratio

Best ResponseYou've already chosen the best response.11 * 2 = 2 2 * 2 = 4 4 * 2 = 8 8 * 2 = 16 16 * 2 = 32 you just multiply the last number in the sequence by 2 each time :)

Best ResponseYou've already chosen the best response.116. 32, 64, 128, 256, 512 is the answer [512]

Best ResponseYou've already chosen the best response.0There actually is a formula. an = a1*r^(n1)

Best ResponseYou've already chosen the best response.1@ComputerNerd Like i said, its a arithmetic sequence

Best ResponseYou've already chosen the best response.0Write the common ratio for the sequence: 12,6,3,\frac{3}{2},... Write the number only. I'm stuck on this one as well

Best ResponseYou've already chosen the best response.1Either you can do this logically or the arithmetic sequence formula

Best ResponseYou've already chosen the best response.0Identify the 10th term for the sequence: 12,6,3,\frac{3}{2},... Write the answer as an integer or fraction. I'm stuck on this one as well

Best ResponseYou've already chosen the best response.0it's the same pattern as the other

Best ResponseYou've already chosen the best response.1@ComputerNerd I noticed when I was using the formula

Best ResponseYou've already chosen the best response.13/4, 3/8, 3/16, 3/32, 3/64, 3/128 is the answer, 3/128, by the way, Geometric sequences have to do with Multiplying/Dividing patterns, Arithmetic has to do with Adding / Subtracting

Best ResponseYou've already chosen the best response.1or you could just do it the easy way @Aliypop and do what I said... Lol @ComputerNerd you don't always need to do the formula if there's a simpler way

Best ResponseYou've already chosen the best response.0@Jadeishere It's always best to know the formula. Your method is okay for terms lower in the sequence but would take too long for terms like 100th term.
