[FREE] Consider the sequence {4, 6, 8, 10, ...}. Find the explicit ...
The explicit formula for the sequence {4, 6, 8, 10, ...} is A) a n = 2 n + 2. This is derived from recognizing that the sequence is arithmetic with a common difference of 2. By substituting the known values into the formula for arithmetic sequences, we confirmed the formula generates the correct terms for the sequence.
找规律,4 6 8 10 第n个数有过程,越详细越好_作业帮
2 + 2n 这很明显...过程就是如果这个数列是2 ,4 ,6,8,10的话,那么就是2n对吧,现在没有2,第一个数从4开始,所以就加一个2上去
