Answer: [tex]a_n=6n-2[/tex]
Step-by-step explanation:
a₁, ____, 16, ____, a₅, _____, a₇
The difference of a₇ and a₅ is 2d (two steps to the next term).
It is given that 2d = 12 --> d = 6
We can subtract 6 from a₃ to find a₁
a₁ = 4, 10, 16, ____, a₅, _____, a₇
Input a₁ = 4, d = 6 into the explicit formula for an arithmetic equation.
[tex]a_n=a_1+d(n-1)\\\\a_n=4+6(n-1)\\\\a_n=4+6n-6\\\\\large\boxed{a_n=6n-2}[/tex]
