Wrong formula. This is an infinite geometric series, so uselionel messi. said:S=(a(rn-1))/(r-1) for r>1
ive all the values except for "n"..can someone help...:/
A sequence is a collection of numbers, arranged in a specific order, that follows a certain pattern or rule. Each number in a sequence is called a term.
A series is the sum of the terms in a sequence. It is represented by the Greek letter sigma (Σ) and the terms are added together using the given pattern or rule.
In an arithmetic sequence, the difference between consecutive terms is constant. For example, 2, 4, 6, 8,... In a geometric sequence, the ratio between consecutive terms is constant. For example, 2, 6, 18, 54,...
To find the nth term of a sequence, you can use the formula an = a1 + (n-1)d for an arithmetic sequence, where a1 is the first term and d is the common difference. For a geometric sequence, the formula is an = a1 * r^(n-1), where a1 is the first term and r is the common ratio.
A series is convergent if the limit of the sequence of partial sums approaches a finite number. In other words, if the terms of the series get closer and closer to a specific value, the series is convergent. If the limit does not exist, the series is divergent.
