The first series is an arithmetic sequence with a common difference 2, for the second series is an arithmetic sequence with a common difference 1.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
For the first sequence:
2, 4, 6, 8, 10
The above sequence represents the arithmetic sequence
The common difference = 4 -2 = 8 - 6 = 2
For the second series:
1, 2, 3, 4, 5
The above sequence represents the arithmetic sequence
The common difference = 2 -1 = 4 - 3 = 1
Thus, the first series is an arithmetic sequence with a common difference 2, for the second series is an arithmetic sequence with a common difference 1.

The sum of the arithmetic sequence given by
<span>an = 0.05(n – 1) – 0.6
will be given by:
a1=0.05(1-1)-0.6=-0.6
a2=0.05(2-1)-0.6=-0.55
a3=0.05(3-1)-0.6=-0.5
a4=0.05(4-1)-0.6=-0.45
a5=0.05(5-1)-0.6=-0.4
thus the summation will be:
-0.6+(-0.55)+(-0.5)+(-0.45)+(-0.4)
=-2.5
hence
S5=-2.5</span>
