An example of 12.1 arithmetic sequences algebra 2 question is Find the sum of the arithmetic series given as 1,2,3…..99,100.
<h3>What is Arithmetic sequences?</h3>An arithmetic sequence is known to be a group or sequence of numbers that is said to be the difference that exist between any two successive members of the sequence and it is a constant.
To find the sequence, one was given a total of 100 values:
So n=100.
first value = 1
Last = 100.
=100/2 (1+100)= 5050
Therefore the answer is 5050
