x is any integer except for -1
If you substitute -1 for x, the denominator value would be 0, or undefined.
For this reason, x cannot be -1, which is mathematically known as an extraneous value.
10+2(50-1)
This is an arithmetic sequence
We know the first term a1 = 10
The common difference, d = 2
an = a1+d(n-1)
We want to find the number of terms when n = 50
a50 = 10+2(50-1)
Answer:b
