Question bank: Sequences: Missing Elements

Joãozinho was playing with building blocks and organized them in a row. He started with 1 block, then placed 2 blocks, then 3 blocks, and so on. But he got distracted and forgot how many blocks he should put after 5. Can you help Joãozinho? How many blocks should he put in the sequence after 5?

Imagine you have a queue of marbles. Each marble has a number. The first one has the number 1, the second one has the number 2, and so on. Now, some marbles have disappeared and you need to find out their numbers. The numbers of the marbles that are left are: 1, 2, 3, 5, 6, 8, 9. What are the numbers of the marbles that disappeared?

In the wall of your classroom, the teacher placed a sequence of colored geometric figures. The sequence started with a yellow triangle, then a blue circle, and so on. However, the teacher forgot to place one of the figures in the middle, and the sequence continued with a red square. Use logic to discover which geometric figure is missing in the sequence and write down what it is. Remember to think about the pattern of colors and shapes to find the correct answer.

In today's class, we learned about sequences, which are sets of things that follow a pattern. It can be a sequence of numbers, like 2, 4, 6, 8, where we always increase by 2, or even a sequence of shapes, like circle, circle, square, circle, square... It's like telling a story with things, but some parts of it are missing! To help João complete the story of the sequences, you need to write down the missing numbers or shapes in the sequences below. Remember to observe the pattern carefully to find out what comes next. Sequence 1: 5, 10, 15, ___, 25, 30, ___. Sequence 2: circle, square, circle, ___, square, circle, ___.

In a Math class, teacher Ana organized a challenge for her students based on mathematical sequences and rhyming words. She presented a sequence of words where the last letter of each word was the same as the first of the subsequent word. The sequence started with the word 'sun', and the students had to figure out which word would correctly complete the sequence, knowing that the theme of the class was about planets in the solar system. The sequence given by teacher Ana was: sun, ...
