PLZ HELP MEDAL WILL BE GIVEN 1)Give the next two numbers in this sequence: 2, 5, 8, 11, ___, ___ 2)Give the 50th number in the sequence. You must show your work. 3)Write an equation to describe this sequence. You must show your work. 4)create a new problem on sequences and give a complete explanation for the answer.
The first one, each number is increasing by 3... I had a huge thing written out then ralized it didn't even make sense to me so I deleted it haha..
Sorry bro.... maybe you could tag someone you know thats smart
wouldnt this sequence just be 3x + 2 .. .then that gives u the number at any of them?
starting with the zeroth term
3x+2 and i can use tht for all of them?
you would plug in 49 for the 50th term though
ok, thanxs can yu help me wit the others?
all you have left is number 4, so for that think of a linear equation and write it as a progression
i should say, write out the y values for the corresponding x = {1,2,3 ... n-1, n} as a progression
so if you choose 2x + 1, then for x = {0,1,2,3} you would write the progression y = {1,3,5,7}
does that make sense? your just plugging in values, y is just x augmented by a function (in this case 3x + 2)
umm ithink i got it, not sure tho
i can walk you though it if you want
a progression is just a sequence of numbers with equal spacing, like 0,1,2,3,4 is each term plus 1
thinkk of this as your x axis, 0,1,2,3...exc,
what a function does is takes this progression and relates it to another progression, 3x for example is a function that takes each number on your x axis and multiplies it by three
so your second progression, think of it as your y axis, is really just the x axis multiplied by three
