Answer:

<em>Survival of the Fittest</em>

There has been gradual evolution of life forms with new forms arising at different periods of history. Any population has built-in variations in characteristics which adapt it better to environment.
The characteristics which enable some population or individuals to survive better in natural conditions (climate, food, physical factors) would out-breed others (Survival of the fittest).
Adaptability is inherited and fitness is the end result of ability to adapt and get selected by nature.

Correct Answer:
Second option

Solution:
The given sequence is:

2.2, 6.6, 11, ...

If we observe the sequence it is an Arithmetic Sequence as the difference between two consecutive terms is the same.

6.6 - 2.2 = 4.4
11 - 6.6 = 4.4

First we find the general term for this sequence.

$a(n)= a_{1}+(n-1)d$

$a_{1}=$ first term = 2.2
d = 4.4

So,

$a(n) = 2.2 +(n-1)*4.4 \\ \\ 
a(n) = 2.2 + 4.4n - 4.4 \\ \\ 
a(n) = 4.4n - 2.2$

This general term will be placed inside the summation sign with limits from 1 to 5 to give the sum of first 5 terms of the given sequence. So the correct answer is Second Option

Answer:

4a-4b

Step-by-step explanation:

In the numerator, we can simplify this: (2a-2b)^2 = ((2)(a-b))^2 = (2)^2(a-b)^2 = 4(a-b)^2 = 4 (a-b)(a-b). Thus, we get: (4(a-b)(a-b))/(a-b). We can cancel the top and bottom with a-b and get: 4(a-b) = 4a-4b.

I hope this helps!
