Write an explicit formula for a(n) the n^th term of the sequence 23, 31, 39, ...

= 8n + 15

Step-by-step explanation:

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

d = 39 - 31 = 31 - 23 = 8

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 23 and d = 8, thus

= 23 + 8(n - 1) = 23 + 8n - 8 = 8n + 15 ← explicit formula

the answer is vanilla

step-by-step explanation:

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
