Q. 11 is a ______ number.

If $11$ and $3$ are factors of a number, then $11 \times 3 = 33$ is also a factor of that number.

Let $a_{1}, a_{2}, a_{3}, . . . ., a_{11}$ be real numbers satisfying $a_{1} = 15, 27 - 2 a_{2} > 0$ and $a_{k} = 2 a_{k - 1} - a_{k - 2}$ for k = 3, 4, ….11. If $\frac{a_{1}^{2} + a_{2}^{2} + a_{3}^{2} + . . . . a_{11}^{2}}{11} = 90$ , then $\frac{a_{1} + a_{2} + a_{3} + . . . . . a_{11}}{11}$ is equal to

Fibonacci numbers Take 10 numbers as shown below:

a, b, (a + b), (a + 2b), (2a +3b), (3a + 5b), (5a +8b), (8a +13b), (13a + 21b), and (21a +34b).

Sum of all these numbers =11(5a + 8b) =11 $\times$ 7th number.

Taking a = 8, b= 13; write 10 Fibonacci numbers and verify that sum of all these numbers =11 $\times$ 7th number.
