- Yey that's great!! when will we Meet?
- Yes ofcourse.
- Actually i'm not doing fine. we're learning about Arithmetic sequence in math and i'm so confused!
- Hi Ellyza how are you?
- Oh! I have a friend who can teach you.
- How about later? I'll just text you is that okay?
- I don't know how to determine if a sequence is an arithmetic sequence let alone how to determine the pattern of one.
- The common difference? what does that mean?
- Ok, well you need to fine the common difference of the pattern.
- a, a ......1 2
- 4,6,8,10
- The common difference is the pattern beetweem the number in an arithmetic sequence. so, if we have a sequence of numbers such as 4,6,8,10 we'd take the 2nd number and subtact the 1st number.
- d=6-4 =4d=8-6 =2d=10-8 =2
- D= Common difference d= a -a 2 1
- it is an arithmetic sequence.
- a, a ......1 2
- 4,6,8,10
- so then, how would we determine if isn't an arithmetic sequence
- So the common difference of this of this sequence number would be 2 because of the common difference is the same throughout.
- The common difference would not be the same throughtout. The common difference has to be the same for it to be an arithmetic sequence.
- d=6-4 =4d=8-6 =2d=10-8 =2
- D= Common difference d= a -a 2 1
- it is an arithmetic sequence.
- 4,7,1,14
- Well, the common difference is 3 beetween the first two sets of number but not the third, so it isn't an arithmetic sequence
- Oh ok!
- d= 7-4 =3d= 10-7 =3d= 14-10 =14
- here you try. Your sequence of number are 4,7,10,14
- it is NOT an arithmetic sequence.
- 4,7,1,14
- Oh ok, That's not bad! They're pretty fun actually!!
- d= 7-4 =3d= 10-7 =3d= 14-10 =14
- Exactly! See you got it!!
- it is NOT an arithmetic sequence.
