The terms in answer (A) are not evenly spaced. The terms are irrational, so the increments shown below are all rounded to the tenths place. Stop after you have confirmed that any two of the jumps are not equal; don’t calculate all of them.
The terms in answer (B) are evenly spaced. Each term is four less than the prior term.
The terms in answer (C) are evenly spaced. Simplify them; each term is one greater than the prior term.
The terms in answer (D) are not evenly spaced. Stop after you have confirmed that any two of the jumps are not equal; don’t calculate all of them.
The terms in answer (E) are evenly spaced. The increment is a variable, but it is a consistent change each time.
Answer: B,C,E
