Geometric progression does not relate to harmonic progression, as harmonic progression is defined through the reciprocals of an arithmetic progression.

Algorithm is unrelated to literature, while the others are key components of storytelling.

'Narrative' refers to storytelling, which is not a scientific term, while the others are integral to the research process.

The terms 1/2, 1/3, 1/4, and 1/5 are in harmonic progression, but 1/6 does not fit as its reciprocal does not maintain the arithmetic progression.

Algorithm is a mathematical term and does not pertain to literary devices like the other three options.

Philosophy is not a technological term, while the others are related to advancements in technology.

'Ecosystem' refers to a biological community, while the other terms are related to technology and data analysis.

'Algorithm' is a term from computer science, while the others are related to health and well-being.

'Isolation' suggests separation and is contrary to the collaborative nature of effective leadership.

Runs is the action word in the sentence, making it the verb.

'Sit' is a stationary action, while the others are active movements.

Carrot is a root vegetable, while the others are fruits.

Simple Interest = Principal × Rate × Time = 2000 × 0.04 × 5 = $400.

'110' in base-2 = 1*2^2 + 1*2^1 + 0*2^0 = 4 + 2 + 0 = 6.

'1010' in binary is 1*8 + 0*4 + 1*2 + 0*1 = 10.

'1010' in binary is 10 in decimal, which is represented as 'A' in hexadecimal.

The pattern suggests that '123' corresponds to 'XYZ', so '456' corresponds to 'DEF'.

Following the same pattern, '7' = 'U', '8' = 'V', '9' = 'W'.

321 is the reverse of 123, thus it represents CBA.

'H' = 8, 'E' = 5, 'L' = 12, 'L' = 12, 'O' = 15; so 'HELLO' = '851212'.

'B' = 2, 'A' = 1, 'D' = 4; sum = 2 + 1 + 4 = 7.

'A' represents 10, so 'B' represents 11 in decimal.

'A' = 10 in decimal, '5' = 5 in decimal. Their sum is 10 + 5 = 15.

In base-7, 'A' = 5*7^1 + 0*7^0 = 35 + 0 = 50 in decimal.

'A' (10) + 5 = 15, which is 'F' in hexadecimal.

In base-4, '22' equals 2*4^1 + 2*4^0 = 8 + 2 = 10.

'43' in base 5 is calculated as 4*5^1 + 3*5^0 = 20 + 3 = 23.

If A is a parent of B and B is a parent of C, then A is C's grandparent.

H=8, E=5, L=12, L=12, O=15. Therefore, HELLO = 85121215.

'C' = '$', 'A' = '@', 'B' = '#', so 'CAB' = '@#$'.
