Question

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.

Answer 1

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..

Answer 2

lol funny

Answer 3

Sorry bro.... maybe you could tag someone you know thats smart

Answer 4

@precal

Answer 5

wouldnt this sequence just be 3x + 2 .. .then that gives u the number at any of them?

Answer 6

3x+2

Answer 7

sry lol, your right

Answer 8

starting with the zeroth term

Answer 9

3x+2 and i can use tht for all of them?

Answer 10

you would plug in 49 for the 50th term though

Answer 11

ok, thanxs
can yu help me wit the others?

Answer 12

all you have left is number 4, so for that think of a linear equation and write it as a progression

Answer 13

i should say, write out the y values for the corresponding x = {1,2,3 ... n-1, n} as a progression

Answer 14

so if you choose 2x + 1, then for x = {0,1,2,3} you would write the progression y = {1,3,5,7}

Answer 15

ok thanxs

Answer 16

does that make sense? your just plugging in values, y is just x augmented by a function (in this case 3x + 2)

Answer 17

umm ithink i got it, not sure tho

Answer 18

i can walk you though it if you want

Answer 19

sure

Answer 20

a progression is just a sequence of numbers with equal spacing, like 0,1,2,3,4 is each term plus 1

Answer 21

thinkk of this as your x axis, 0,1,2,3...exc,

Answer 22

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

Answer 23

so your second progression, think of it as your y axis, is really just the x axis multiplied by three

Answer 24

ok
