The 31st term of this arithmetic sequence is equal to 97.
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.
