Answer:
The explicit formula for the given expression is 2 n - 3
Step-by-step explanation:
Here, the first term of sequence = -1
The common difference = 2
In a ARITHMETIC PROGRESSION:
The nth term of a sequence is given as
a(n) = a + (n-1) d
⇒ Here, a(n) = -1 + (n-1)(2)
= -1 + 2n -2
= 2n - 3
or, a(n) = 2n - 3
Hence, the explicit formula for the given expression is 2n - 3.
