六年级上册递等式计算题目
以下是一些递等式计算题目:
1.计算:1×3+2×3+3×3+...+10×3
解:这是一个等差数列,首项为1×3,公差为1,项数为10。首项:a₁=1×3=3
公差:d=1
项数:n=10
根据等差数列求和公式:Sn=n/2×(2a₁+(n-1)×d)
代入值计算:S10=10/2×(2×3+(10-1)×1)
=10/2×(6+9)
=10/2×15
=5×15
=75
所以,1×3+2×3+3×3+...+10×3=75
2.计算:5+9+13+17+...+37
解:这是一个等差数列,首项为5,公差为4,末项为37
首项:a₁=5
公差:d=4
末项:aₙ=37
由等差数列求和公式可以知道:Sn=n/2×(a₁+aₙ)
我们需要找到末项对应的项数n。
aₙ=a₁+(n-1)×d
37=5+(n-1)×4
32=(n-1)×4
8=n-1
n=9
代入值计算:S9=9/2×(5+37)
=9/2×42
=4.5×42
=189
所以,5+9+13+17+...+37=189
3.计算:2²+3²+4²+...+8²。
解:这是一个等差数列,首项为2²,公差为1,末项为8²。首项:a₁=2²=4
公差:d=1
末项:aₙ=8²=64
由等差数列求和公式可以得知:Sn=n/2×(a₁+aₙ)
我们需要找到末项对应的项数n。
aₙ=a₁+(n-1)×d
64=4+(n-1)×1
63=(n-1)×1
n=64
代入值计算:S64=64/2×(4+64)
=32×68
=2176
所以,2²+3²+4²+...+8²=2176
这些都是一些递等式计算题目,你可以尝试解答,如果有疑问的话,我可以帮助你解答。
