18 Αυγ 2024 · Sum of first n Odd Numbers is calculated by adding together integers that are not divisible by 2 from 1 to n, it can be easily calculated by using the formula, resulting in a total that is either an odd number or even number.
The Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic Sequence Formula: an = a1 +d(n −1) a n = a 1 + d (n - 1) Geometric Sequence Formula: an = a1rn−1 a n = a 1 r n - 1.
The odd numbers form an arithmetic sequence with \(a=1\) and \(d=2\). The \(n\) th term is \(a_{n}=1+2\left(n-1\right)=2n-1\) so, the \(50\) th odd number is \(a_{50}=2\left(50\right)-1=99\). Substituting in Formula \(2\) for the partial sum of an arithmetic sequence, we get
an = a1 + (n − 1)d = 4 + (n − 1) ⋅ 5 = 4 + 5n − 5 = 5n − 1. Therefore, the general term is an = 5n − 1. To calculate the 50 th partial sum of this sequence we need the 1 st and the 50 th terms: a1 = 4 a50 = 5(50) − 1 = 249. Next use the formula to determine the 50 th partial sum of the given arithmetic sequence.
