Directions to Solve: Look carefully for the pattern, and then choose which pair of numbers comes next.
Explanation:
Here, every other number follows a different pattern. In the first series, 6 is added to each number to arrive at the next. In the second series, 10 is added to each number to arrive at the next.
Directions to Solve: Look carefully for the pattern, and then choose which pair of numbers comes next.
Explanation:
This is an alternating addition series, in which 10 is added, then 5, then 10, and so on
