STEP - BY - STEP EXPLANATION

What to find?

Determine if the given series is;

Geometric or arithmetic?

Finite or infinite.

Given:

-1+0+1+2+3+4+5+6+7+8

Observe from the above that ;

first term =-1=a

Common difference (d) = 2-1 = 1

Since what we have is a common difference and not a common ratio, then the series is an arithmetic series.

Also, observe that , the series keeps increasing by 1. Hence, it is an infinite series.

ANSWER

arithmetic

infinite
