What is an arithmetic sequence?

An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.

How to calculate an arithmetic sequence?

Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:

aₙ =  a₁ + (n - 1)d

Where:

  • d is the common difference.
  • a₁ is the first term of an arithmetic sequence.
  • n is the total number of terms.

How to determine the 31st term?

aₙ = 7 + 3(n - 1)

a₃₁ = 7 + 3(31 - 1)

a₃₁ = 7 + 3(30)

a₃₁ = 7 + 90

a₃₁ = 97.
