Answer:
2n - 12
Step-by-step explanation:
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = -10
n is the number of terms
d is the common difference = 2
Substitute
Tn = -10 + (n-1)2
Tn = -10 + 2n-2
Tn = 2n -10-2
Tn = 2n - 12
Hence the nth term of the sequence is 2n - 12
