Question

Identify the following series as geometric or arithmetic. Also identify the series as infinite or finite.

-5, -10, -15, -20,
arithmetic
geometric
infinite
finite

I thought it would be arithmetic, infinite. But I am just wanting to check!

Answer 1

it might be good to know that multiplication tabels are arith sequences

now you ask if a sequence of numbers is a series ... which it aint. a Series is a summation of a sequance of numbers

Answer 2

I'm a little confused.. Are you saying that what makes it an arithmetic series is the multiplication? & they call it a series..

Answer 3

no, just making some side notes

multiplication tables are arithmetic sequences

and you asked if the given is a series - a series is defined as the sum of the terms of a sequence. And yet posted a sequence of terms and not a series

Answer 4

It would be arithmetic sequence because the common difference is the same in the consecutive integers.... So it is arithematic progression. as fas as it is concerned that it is a series or not, it is given a sequence not a series.....

Answer 5

sequence: 1,2,4,8,16,...

series: 1+2+4+8+16+...

Answer 6

Okay, that makes sense. Thank y'all (:
