1.2.2 Sum of Consecutive Prime Numbers 描述:一个正整数可以表示为一个或者多个连续素数的和。比如 53 有两种表示方法53 和 5+7+11+13+17,但是 20 的 7+13 就不能满足条件,因为7和13并不是连续的素数。 输入:输入一个正整数序列,每个数一行,在2-10000之间取值。输入结束以0表示 输出:输出的每一行对...

The sum of all natural numbers less than 400 which are NOT divisible by 6, is View Solution The number of all prime numbers less than 40 is .. View Solution If N is the sum of first 13,986 prime numbers, then N is always divisible by View Solution How many natural numbers less than...
To determine the divisibility of the sum N of the first 13986 prime numbers, we can follow these steps: Step 1: Identify the first prime numberThe first prime number is 2. Step 2: Identify the nature of the remaining prime numbersAll subsequent prime numbers after 2 are odd. Therefore,...
Sum of first n odd numbers: Let’s look at the formula for the sum of n odd natural integers. The sequence of odd numbers is written as 1, 3, 5,…(2n – 1), forming an arithmetic progression with a common difference of 2. Let Sn = 1 + 3 + 5 +…+ be the sum of the firs...
