Question 1092409: Can someone help? Thank you.
Write the sum using summation notation, assuming the suggested pattern continues.
1+8+27+...+(n+1)^3
I solved like this: ∑(k+1)^3 (top of sigma sign: n, bottom of sigma sign: k=0). I could not write it properly here...
Please fix this if I am wrong.

You can either write it this way:

sum%28%28k%2B1%29%5E3%2Ck=0%2Cmatrix%281%2C3%2C%22%22%2C%22%22%2Cn%29%29

or you can write it this slightly simpler way:

sum%28k%5E3%2Ck=1%2Cmatrix%281%2C2%2C%22%22%2Cn%2B1%29%29

Both are equal to 1+8+27+...+(n+1)^3
