Find the next term in the sequence: 5, 12, 10, 16, 20, 20, 40, ?
In a 3x3 arithmetic grid, Row 1 has (4, 9, 26) with rule (2 x 4) + (2 x 9) = 26. Row 2 has (3, 7, 20) with rule (2 x 3) + (2 x 7) = 20. Row 3 has (5, 6, ?). What is the missing number?
On a balanced scale, 2 cubes and 1 cylinder weigh the same as 8 small metal balls. If 1 cylinder weighs the same as 2 cubes, how many metal balls weigh the same as 1 cube?
Parent Home Practice Checklist
- Help your child memorize squares up to 20x20 and cubes up to 10x10 to recognize quadratic series immediately.
- Teach your child to write differences between consecutive terms above each number when testing an unfamiliar sequence.
- Ensure your child never spends more than 45 seconds on any single sequence question before guessing and moving on.
