What have you learned about arithmetic sequence?
What have you learned about arithmetic sequence?I need help on the first question
Not much, but normally I can solve a question given the terms but this question doesn’t give terms in the sequence so I am not really sure the steps in solving this. Normally I would find the pattern and then apply it to any numbers I need to find but this isn’t the case.What have you learned about arithmetic sequence?
Start here:Not much, but normally I can solve a question given the terms but this question doesn’t give terms in the sequence so I am not really sure the steps in solving this. Normally I would find the pattern and then apply it to any numbers I need to find but this isn’t the case.
Do you know the answer of the question posed above?If 'a' is the first number of the sequence and 'd' is the common difference -do you know the expression for 'n' th element of the sequence?
If you don't understand a the level of what they are asking then why have you been asked the question?I’m sorry, but I’m only an year 7 so I don’t really understand all these symbols. Sorry once again if it takes too much time to explain. Sorry
So, what symbols do you understand? That's why you need to show us what you have learned.I’m sorry, but I’m only an year 7 so I don’t really understand all these symbols. Sorry once again if it takes too much time to explain. Sorry
Would it be 10a0+ 45?If you don't understand a the level of what they are asking then why have you been asked the question?
The sum of the first 10 terms in the sequence:
[math](a_0) + (a_0 + d) + (a_0 + 2d) + \text{ ... } + (a_0 + 9d)[/math] is what? Write it out and combine like terms.

10a0+45 =Would it be a0+ 45?
Yes, I think so. To find the common difference generally you subtract two terms from each other.Do you know the answer of the question posed above?
We are trying to figure out the first step of the explanation - so that it will make sense to you.
I think you are misunderstanding the question.Yes, I think so. To find the common difference generally you subtract two terms from each other.
So what A would be?Do you know the answer of the question posed above?
