Answer:
It is not. A multiplicative inverse is the reciprocal for a number. For a fraction, the form would change from a/b to b/a. In this case the multiplicative inverse of 7/8 would be 8/7.
It’s 11 because -7 + 11 equals to 4.

I couldn't post images for 6, it wont let me.
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4 gives the next term. In other words:
an = a1 * r ^ (n-1)
Now, knowing that a1 = 2, and r = 4
We check
a2 = 2 * 4 ^ (2-1) = 2 * (4 ^ 1) = 8
a3 = 2 * 4 ^ (3-1) = 2 * (4 ^ 2) = 32
a4 = 2 * 4 ^ (4-1) = 2 * (4 ^ 3) = 128
Therefore, this is the geometric function that this sequence fulfills.
