Rick ans chad are playing a number pattern game. rick wrote the pattern.
32.3, 34.5, 36.7, _, 41.1 what is the unknown number in the pattern rick wrote? a) 37.9 b) 38.8 c)38.9 d) 39.9 what is the answer

Find the rate of change between terms to see if it is linear, a higher order, or exponential sequence...

34.5-32.3=2.2, 36.7-34.5=2.2, (41.1-36.7)/2=2.2

So this is a linear sequence with a common difference, or constant velocity, of 2.2.  The first term is 32.3 and the rate is 2.2 so the linear equation is:

y=32.3+2.2(x-1) or more neatly

y=2.2x+30.1 so the fourth term is:

y(4)=2.2(4)+30.1

y(4)=38.9
