Let 'N' be the number. The sum of the number and 13 is (N+13).The square of the sum of the number and 13 is (N+13)2N2 + 26 N + 169.It's probably easier to add 13 to the number and then square that answer ... less arithmetic.
To find the sum of the series of the first 20 positive integers ending in 3, we first need to identify the pattern. The series would be 3, 13, 23, 33, ..., 193. This is an arithmetic series with a common difference of 10. To find the sum, we can use the formula for the sum of an arithmetic series: n/2 * (first term + last term), where n is the number of terms. Plugging in the values, we get 20/2 * (3 + 193) = 10 * 196 = 1960. Therefore, the sum of the series is 1960.
