# In Problems 20-25, use the sum formulas I-V to express each of the following without the summation symbol. In Problems 20-23, find the numerical value. ∑ j = 1 60 3

To determine

To calculate: The expression of j=1603 without the summation symbol and find its value.

Explanation

Given Information:

The provided sum is j=1603.

Formula used:

The sum of n numbers x1, x2, x3,,xn is given by

k=1nxk=x1+x2++xn

The value of the sum k=1n1 is n.

k=1n1=n

The value of the sum k=1ncxk=ck=1nxk.

Calculation:

Consider the sum j=1603.

Recall the value of the sum k=1ncxk=ck=1nxk.

Thus, j=1603=3j=1601.

The sum of n numbers x1, x2, x3,,xn is given by k=1nxk=x1+x2++xn
