Geometric Sequences; Formula and Common Ratio: A geometric sequence is written as per the below general form: $$a,ar,ar^{2},ar^{3},... $$ For a geometric sequence, all terms are non-zero. where {eq}a {/eq} is the first term {eq}r {/eq} is the ...
如果p=1.r=2.s=3,t=6,u=12.如果都减去3,就成了-2,-1,0,3,9了,就不符合了。 答案 arithmetic sequence是等差数列的意思如果是等差数列那么I和II肯定符合啊I:an=a1+(n-1)d那么2an=2a1+(n-1)*2*d,则首项为2a1,公差为2d的等差数列II:an=a1+(n-1)dan-3=a1-3+(n-1)d,则首项为a1-...
=12(n−1)+5 =5+(n−1)12 T(n) can be expressed in the form of a+(n−1)d. Thus, the sequence is a arithmetic sequence. T(n)能以a+(n−1)d的方式表示,因此该数到为等差数列. Tips:若T(n)能以an+b的方式表示,该数列便是等差数列A.S.. 因此选项Ⅲ错误. 反馈 收藏 ...

Sequence: In mathematics, we have two important types of sequences: Arithmetic sequence and Geometric sequence. In arithmetic sequence, the difference between the two terms i.e. any term of sequence and its previous term is the same whereas, in a geometric sequence, the ...
These problems take between 2 and 8 steps to solve, and solutions primarily involve performing a sequence of elementary calculations using basic arithmetic operations (+ − ×÷) to reach the final answer. A bright middle school student should be able to solve every problem. "We initially coll...
