Consecutive Prime Sum

The prime $41$, can be written as the sum of six consecutive primes: $$41 = 2 + 3 + 5 + 7 + 11 + 13.$$ This is the longest sum of consecutive primes that adds to a prime below one-hundred. The longest sum of consecutive primes below one-thousand that adds to a prime, contains $21$ terms, and is equal to $953$. Which prime, below one-million, can be written as the sum of the most consecutive primes?

Prime Permutations

The arithmetic sequence, $1487, 4817, 8147$, in which each of the terms increases by $3330$, is unusual in two ways: (i) each of the three terms are prime, and, (ii) each of the $4$-digit numbers are permutations of one another. There are no arithmetic sequences made up of three $1$-, $2$-, or $3$-digit primes, exhibiting this property, but there is one other $4$-digit increasing sequence. What $12$-digit number do you form by concatenating the three terms in this sequence?

Distinct Primes Factors

The first two consecutive numbers to have two distinct prime factors are: - 14 = 2 × 7 - 15 = 3 × 5 The first three consecutive numbers to have three distinct prime factors are: - 644 = 2² × 7 × 23 - 645 = 3 × 5 × 43 - 646 = 2 × 17 × 19 Find the first four consecutive integers to have four distinct prime factors each. What is the first of these numbers?

Goldbach's Other Conjecture

It was proposed by Christian Goldbach that every odd composite number can be written as the sum of a prime and twice a square. - 9 = 7 + 2 × 1² - 15 = 7 + 2 × 2² - 21 = 3 + 2 × 3² - 25 = 7 + 2 × 3² - 27 = 19 + 2 × 2² - 33 = 31 + 2 × 1² It turns out that the conjecture was false. What is the smallest odd composite that cannot be written as the sum of a prime and twice a square?

Triangular, Pentagonal, and Hexagonal

Triangle, pentagonal, and hexagonal numbers are generated by the following formulae: Triangle: T_n = n(n+1)/2, sequence: 1, 3, 6, 10, 15, ... Pentagonal: P_n = n(3n-1)/2, sequence: 1, 5, 12, 22, 35, ... Hexagonal: H_n = n(2n-1), sequence: 1, 6, 15, 28, 45, ... It can be verified that T285 = P165 = H143 = 40755. Find the next triangle number that is also pentagonal and hexagonal.
