The given sequence is an arithmetic sequence with a common difference of 2.

To find the 20th term, we can use the formula:

an = a1 + (n - 1)d

where
an is the nth term of the sequence
a1 is the first term of the sequence
d is the common difference between the terms
n is the term we want to find

We are given that a1 = -6, d = 2, and n = 20. Substituting these values into the formula, we get:

a20 = -6 + (20 - 1)2
a20 = -6 + 38
a20 = 32

Therefore, the 20th term of the sequence is 32.

Explanation:

Arithmetic sequence with d = 2 a1 = -6

a20 = -6 + 2(20-1) = 32
