Math Problem Statement

if 1 is 5, 2 is 8, 3 is 11 and 4 is 14. What is n?

Solution

This appears to be a pattern where each value increases by 3 as the input increases by 1. Let's analyze this:

  • When 151 \rightarrow 5
  • When 282 \rightarrow 8
  • When 3113 \rightarrow 11
  • When 4144 \rightarrow 14

We can observe that each output is increasing by 3 compared to the previous one, which suggests a linear relationship between the input nn and the output f(n)f(n).

We can describe this relationship as a linear equation:

f(n)=3n+2f(n) = 3n + 2

Derivation:

  • For n=1n = 1, f(1)=3(1)+2=5f(1) = 3(1) + 2 = 5
  • For n=2n = 2, f(2)=3(2)+2=8f(2) = 3(2) + 2 = 8
  • For n=3n = 3, f(3)=3(3)+2=11f(3) = 3(3) + 2 = 11
  • For n=4n = 4, f(4)=3(4)+2=14f(4) = 3(4) + 2 = 14

Thus, for any nn, the corresponding value is given by f(n)=3n+2f(n) = 3n + 2.

If you have a specific value of nn in mind, you can plug it into this equation to find the answer.

Tip: Always look for differences between consecutive terms to identify a pattern type. Linear patterns have constant differences.
