Answer:
Tn = -6 + (n - 1)(-4)
Step-by-step explanation:
The explicit formula is this: Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference.
The first term is given to you and that is -6.
The common difference is -4 because:
d = -10 - (-6)
d = -10 + 6
d = -4
Hence: Tn = -6 + (n - 1)(-4)
