Write the explicit rule,

= 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

= 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12

because 1.2 isnt half of 6 duh
