What is the sum of the first 10 terms of the Fibonacci sequence, starting with 1 and 1, if each term after the second term is the sum of the two preceding terms?

The Fibonacci numbers are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55. The sum of the first 10 terms is 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 + 55 = 143.

Question: What is the sum of the digits in the number 1597 multiplied by the square root of 1597 divided by the cube of the largest prime number less than 1597?

To find the sum of the digits in 1597, we add 1 + 5 + 9 + 7 = 22. Now, we calculate the square root of 1597 as approximately 39.969 or 39.97 (rounded to 2 decimal places). The largest prime number less than 1597 is 1597 itself since it is a prime number. Therefore, the cube of the largest prime number less than 1597 is 1597^3 = 4,060,113,273. Finally, we divide the square root by the cube: 39.97 / 4,060,113,273 ≈ 9.837 × 10^-9. So, when we multiply this value by the sum of the digits (22), we get 9.837 × 10^-9 × 22 ≈ 2.164 × 10^-7. Hence, the final answer is approximately 2.164 × 10^-7.

Math question: What is the largest prime number less than 1597?

To find the largest prime number less than 1597, we start by dividing 1597 by smaller prime numbers. We discover that 1597 is not divisible by 2, 3, 5, 7, ... After trying various primes, we find that 1597 is divisible by no prime numbers. Therefore, 1597 itself is a prime number. Hence, the largest prime number less than 1597 is 1597.
