This sequence has a difference of 5 between each number. The values of a and d are: a = 3 (the first term) d = 5 (the "common difference") Using the Arithmetic Sequence rule: xn = a + d(n−1) = 3 + 5(n−1) = 3 + 5n − 5 = 5n − 2 So the 9th term is:...

For just playing the game, the enjoyment rating is lower for all grades except the youngest. In general students rate teaching the agent as 17 % more enjoyable than only playing the game, and 92 % of the students rated it as fun or okay. Students’ Performances of the Agent-Tutoring Task...
quarters, thirds, et cetera, when separating things is done daily in many households; for example, “Let’s split this apple. You take half and I’ll take the other half.” Asking children to follow the directions involved in simple cooking activities gives them the opportunity to measure,...
which is defined by a sequence of rational approximations. In addition, an important role has been played by the apparatus of decimal fractions and the use of logarithms, which has broadened the range of operations that could be performed with the required accuracy on real numbers, both irrationa...
of arithmetic as a science, adequate for the study of different types of continuous quantities, was realized only at the end of the 17th century in connection with the incorporation into arithmetic of the concept of the irrational number, which is defined by a sequence of rational approximations...
For instance, the novice driver may learn and be potentially aware of the MSM rule (mirror, signal, maneuver), and while later they can follow this sequence very well and automatically, it would be strange to still quote or murmur the acronym once learnt. However, in difficult situations or...
