Finding the nth Term Given a Formula

A sequence is defined by the following:
an = 4n-1
What is a₁?
RETRY
What is ag?
O
RETRY✔

Answer 1

To find the first term of the sequence defined by a formula, substitute the value of n and evaluate the expression.

Step-by-step explanation:

To find the first term, a₁, of the sequence defined by the formula an = 4n-1, we substitute 1 for n:

a₁ = 4(1) - 1 = 4 - 1 = 3

Therefore, the first term of the sequence is 3.
