Algebra 1

geometric sequence

a sequence in which there is a common ratio between the terms

sequence

a set of numbers that follows a pattern, with a specific first number

radical expression

an expression that contains a radical; √7 and √21y are examples of radical expressions

term

an individual quantity or number in a sequence

rationalize

eliminate the radical from the denominator of a fraction

like radicals

expressions having the same root index and the same radicand

exponent

the (superscript) number in an exponential expression which tells how many times a factor is repeated

radicand

the expression under a radical symbol

common ratio

the fixed amount multiplied by a term to get to the next term in a geometric sequence

base

the number which is repeated as a factor in an exponential expression

index

the small number preceding a radical symbol that indicates the desired root of the radicand
