- Look at the graph below. The heights of the bars form a pattern. What height should Bar 5 have?
Answer: 15
The bar heights are 3, 6, 9, 12. The pattern adds 3 each time. After 12, the next height is 12 + 3 = 15.
- In this number pattern, some numbers are missing: 1, 4, ___, 10, 13, ___. If the pattern continues the same way, what are the two missing numbers?
Answer: 7 and 16
The pattern adds 3 each time: 1 + 3 = 4, 4 + 3 = 7, 7 + 3 = 10, 10 + 3 = 13, 13 + 3 = 16. So the missing numbers are 7 and 16.
- Based on the bar graph shown, what should be the height of the last bar to keep the +5 pattern?
Answer: 25
Bar heights show 5, 10, 15, 20, ?. The pattern adds 5 each time. After 20 comes 20 + 5 = 25. The other options break the consistent +5 pattern.
- Based on the graph shown: what is the next number in the pattern?
Answer: 32
The line graph shows points at 8, 16, 24, which increase by 8 each time. Adding 8 to 24 gives 32. Answers B (40), C (48), and D (56) are multiples of 8 but skip steps in the sequence.
- Based on the graph shown, what number should come next in the sequence?
Answer: 8
The bar graph heights are 2, 4, 6, ____ showing a +2 pattern. Adding 2 gives 8, so answer B. 5 and 9 do not follow the +2 rule; 12 skips one step.
- Refer to the chart above. Which number finishes the arrow path?
Answer: 108
Arrow boxes show 100,104,___,112. They add 4. After 104 comes 108. 110 adds 6, etc.
