WebWhen using arithmetic sequence formula. Always do the operation inside the parenthesis first, then multiply the result by the number outside the parenthesis( this is the common difference). Lastly take the product of that operation, and subtract/add (depends on the product!) to the first number ( which is the first term of the sequence. WebAug 18, 2024 · The first principal component (PC1) is the line that best accounts for the shape of the point swarm. It represents the maximum variance direction in the data. Each observation (yellow dot) may be projected onto this line in order to get a coordinate value along the PC-line. This value is known as a score. The second principal component

WebThe explicit formula can be computed from the n th term of the given sequence. The n th term of the arithmetic sequence is a n = a + (n - 1)d and plugging in the value of a and d gives the required explicit formula of the arithmetic sequence.
