MATH 10 QUARTER 1

• sequence - or progression is a list of numbers written in a specified order that follows a definite pattern or rule
• term - each number in the sequence
• first term - first number in the sequence
• arithmetic sequence - is a sequence where every term after the first is obtained by adding a constant called the common difference (d)
• finite sequence - contains a finite number of terms (with first term and last term)
• infinite sequence - contains an infinite number of terms (with first term and no last term)
• arithmetic series - is the sum of the terms of an arithmetic sequence with a definite number of terms
• Carl Friedrich Gauss - introduced the formula
• geometric sequence - a sequence where each term after the first term is obtained by a nonzero constant called the common ratio
• common ratio - a nonzero constant
