Which answer describes the type of sequence? 3, 4, 7, 11, ...

neither arithmetic nor geometric

geometric

arithmetic

Neither arithmetic nor geometric. (I took the quiz)

neither arithmetic nor geometric

Step-by-step explanation:

An arithmetic sequence is a sequence in which each term is found by adding the same constant to each term. Looking at our sequence, to get from 3 to 4 we add 1; to get from 4 to 7 we add 3; and to get from 7 to 11 we add 4. This is not constant, so this is not arithmetic.

A geometric sequence is a sequence in which each term is found by multiplying each term by a constant. Looking at our sequence, to get from 3 to 4 we multiply by 4/3; to get from 4 to 7 we multiply by 7/4; to get from 11 to 7 we multiply by 11/7. These are not equivalent fractions, which means this is not a constant and not a geometric sequence.

Thus this is neither.
