Solve arithmetic problems
You cannot solve a sequence: you can only solve a question about the sequence. The idea is to find the pattern, so you know what comes next.
They used an abacus calculating device to solve complicated arithmetic problems.
There is no way to answer your question. It is not an equation, because there is no equal sign. There is no explanation if it is a sequence of arithmetic or geometric numbers. There is nothing to go on to solve for a value of B.
arithmetic
Finite precision arithmetic, solve numeric errors by using the floating point.
A single number, such as 62496384, does not comprise a sequence!
First, count how much is between each number in the sequence. That is the number you will put in front of the x. 4,5,6,7,8... y=1x+b Secondly, solve for b. In this case x=1 then b must be 3 to make it work.
You cant solve the next term (next number) in this sequence. You need more terms, because this is either a "quadratic sequence", or a "linear and quadratic sequence", and you need more terms than this to solve a "linear and quadratic sequence" and for this particular "quadratic sequence" you would need more terms to solve nth term, which would solve what the next number is. If this is homework, check with your teacher if he wrote the wrong sum.
sum(1/(n^2+1))
By doing the arithmetic.
