Write a mathematical equation for: In a set of data, each number is 2.38 more than the preceding number?

Question

Elementary Math Models

Answer 1

This can be done linearly:

 

y = a₀ + dX

 

where y = value of term

 

a₀ is the zero term (y-intercept of graph)

 

d = common difference between successive terms

 

X = term number

 

Then:

 

Y = a₀ + d(2.38)

Answer 2

a_n+1 = a_n + 2.38
