21,19,16,12....

Step-by-step explanation:

Answer 2

The answer will be 7.

Given:

A series of terms were given

3, 21, 5, 19, 8, 16, 12, 12, 17,?

To Find:

We need to find the next value.

Solution:

The given sequence of terms is arranged based on a certain logic.

The odd terms are obtained by

$3 + 2 = 5$

$5 + 3 = 8$

$8 + 4 = 12$

$12 + 5 = 17$

The even terms are obtained by

$21 -2 = 19$

$19 - 3= 16$

$16 - 4 = 12$

$12 - 5 = 7$

Therefore, the value is 7.
