Starting at the top as you move clockwise around the wheel how do the numbers change(the numbers are 0.8,0.81,0.82,0.83,0.84,0.85,0.86,0 .87,0.88,0.89 and 0.3,0.31,0.32,0.33,0.34,0.35,0.36,0 .37,0.38,0.39)

Individual series:

a) A.P with a = 0.80 and r = 0.01

b) A.P with a = 0.30 and r = 0.01

Combined single series

Step-by-step explanation:

We move from the top in clockwise direction around a wheel to get series of number:

0.8, 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89

If we, notice it carefully it forms an arithmetic progression.

Arithmetic progression is of he form a, a+r, a+2r, a+3r,... and so on.

If we compare it to the given series we get,

a = 0.80

r = 0.81 - 0.80 = 0.01

Thus, every time it increases by 0.01.

The next number of series is given by:

0.3, 0.31, 0.32, 0.83, 0.34, 0.35, 0.36, 0.37, 0.38, 0.39

If we, notice it carefully it forms an arithmetic progression.

a = 0.3

r = 0.31 - 0.30 = 0.01

Thus, every time is increasing by 0.01.

Now, if we consider that it to be a combined single series, then, first the series increases by 0.01 and then 0.5 was subtracted from initial terms to get the corresponding terms of the second part of the series.
