Answer:
Tₓ = 7 + (x-1)(2)
Explanation:
Tₓ = a + (x-1)(d)
a is the first term in the sequence and d is the common difference
In this sequence, the first term is 7.
In this sequence, the common denominator is 2, because 9 - 7 = 2 and 11 - 9 = 2 and so on.
Hence, Tₓ = 7 + (x-1)(2)
*The x is meant to be an n*
