question 1-
a. 5n
b.n x 1 from last week. soooo.. and whatever n is, then it is divisible by that number.
c.it makes logical sense because typically all the formulas are very similar and they all have to just be changed a little to work. so it becomes logical in my opinion.
question 2-
a.
n = 1 - 1 = 1
n = 2 - 1+3 = 4
n = 3 - 1+3+5 = 9
n = 4 - 1+3+5+7 = 16
n = 5 - 1+3+5+7+9 = 25
n = 6 - 1+3+5+7+9+11 = 36
n = 7 - 1+3+5+7+9+11+13 = 49
n = 8 - 1+3+5+7+9+11+13+15 = 64
b. the difference between each number is odd. starting at 3, then 5 then 7.. now do i know how to generate a formula for that? no... oh & multiply the number by itself and you get that number also
c. this is true for all n terms because no matter what the number is if you are asked to find the even sum ... you just multiply the number times itself and get your answer.
You said that you don't know how to generate the formula and yet you outright stated it.
ReplyDelete"multiply the number by itself and you get that number also"
Write that using math rather than words and you're done with that part.
Also, I should note that I am not really sure what your answers mean for question 1.
