Explain is it possible to find the sum of the sequence in this problem.
Your expression needs to be corrected! You posted:
a_{1} = 10
\(\displaystyle a_{[?]} \ = \ a_{n1} + 3\)
On the lefthandside of the equation there is no refernce to a_{n}!
To SUM a sequence, it must either END or CONVERGE (in some appropriate sense).Thanks for your response!
So its not possible to find the sum of this sequence then? a_{n}! is added to the left hand side correct?
Presumably you are asking about finding the sum of the first N terms in the sequence defined byExplain is it possible to find the sum of the sequence in this problem.
a2=3+10=13Presumably you are asking about finding the sum of the first N terms in the sequence defined by
a_{1} = 10
a_{n} = a_{n1} + 3
Write out the first several terms of this sequence, and the corresponding sums, in order to get a sense of what you are working with.
Then look up "arithmetic series", and see if you can apply what you learn. Show us whatever you are able to do, and we'll help you out.
Do you know the sum of first 'n' terms in an arithmatic series with first term 'a' and common difference 'd'?a2=3+10=13
a3=3+13=16
a4=3+16=19
a5=3+19=22
a2a1=1310=3
a3a2=1613=3
a4a3=1916=3
a5a4=2219=3
common difference is 3
Good; you saw where I was leading you. (Did you notice that the definition itself tells you the common difference: a_{n}  a_{n1} = 3 .)a2=3+10=13
a3=3+13=16
a4=3+16=19
a5=3+19=22
a2a1=1310=3
a3a2=1613=3
a4a3=1916=3
a5a4=2219=3
common difference is 3
Not being sure of what really what the question is, I take Prof. Peterson's reading.Explain is it possible to find the sum of the sequence in this problem.
