Answer: 4,900

Explanation:

A positive odd integer is any odd integer greater than zero.

We can use the sum of odd numbers formula where S is the sum and n is the number of terms, as shown below:

$\displaystyle S=n^2$

Since we are finding the sum of the first 70, there are 70 terms:

$\displaystyle S=n^2$

$\displaystyle S=70^2$

$\displaystyle S=4,900$
