What is the general term of the sequence {14,2,14,2......}

what is the general term of this sequence {14,2,14,2,......}

r = -1
a = 14 therefor it's 8+6
n = number of terms
Tn = General term
We will use the formula Tn=ar^n-1
Therefor your general term is.
Tn=ar^n-1
=8+6(-1)^n-1
Put 1 or 2 or 3...in the place of n to verify you sequence.

a_n = 8+6(-1)^n for n = 0, 1, 2, ...
