Letter and Symbol Series

The pattern here: first number increases by consecutive odd numbers (3+3=6, 6+5=11, 11+7=18, 18+9=27). The letter position increases by consecutive numbers (F+1=G, G+2=I, I+3=L, L+4=P). The answer is 27P.

Three patterns: first letter goes back by 2 (K-I-G-E-C), second letter goes forward by 3 (M-P-S-V-Y), number adds 3 each time (5, 8, 11, 14, 17). The missing term is CY17.

Letters go backwards by 2 (W-U-S-Q-O) and numbers are descending perfect squares (12²=144, 11²=121, 10²=100, 9²=81, 8²=64). The missing term is U-121.

Two interlinked patterns: numbers increase by consecutive even numbers (2+2=4, 4+4=8, 8+6=14, 14+8=22) and letters advance by increasing steps (B+1=C, C+2=E, E+3=H, H+4=L). The answer is 22L.

This alternating series has two patterns: numbers go +7, -3, +7, -3 (2+7=9, 9-3=6, 6+7=13, 13-3=10) while letters simply advance one at a time (A-B-C-D). The missing number is 10.

The series has three interwoven patterns. The first letters decrease by 3 (N→K→H→E→B). The numbers follow +2, +3, +4, +5 pattern (5→7→10→14→19). The last letters decrease by 2 (V→T→R→P→N). Only H10R satisfies all three patterns.

The first letters increase by 2 (Q→S→U→W→Y). The last letters decrease by 1 (F→E→D→C→B). The numbers follow n×(n+1)+(n+1): 1, 2, 6, 21, 88. Only Y88B satisfies all three conditions.

The first letters decrease by 2 each time (K→I→G→E→C). The middle numbers increase by 3 (5→8→11→14→17). The last letters decrease by 2 (M→P→S→V→Y). Only CY17 fits all three patterns.

The first letters increase by 3 (C→F→I→L). The middle numbers follow squares: 4, 9, 16, 25. The last letters decrease by 3 (X→U→R→O). L25O is the only option satisfying all patterns.

The series follows three patterns: first numbers are 2, 7, 14, 23, 34, 47 (differences 5, 7, 9, 11, 13 - consecutive odd numbers). Letters decrease by 1 (Z→Y→X→W→V→U). Last numbers increase by 2 (5, 7, 9, 11, 13, 15). Only 47U15 satisfies all.

In each step,both the numbers and letters are taking a forward step of 2. hence the next two letter after J will be L and N and the next two numbers after 10 are 12 and 14.

The first numbers follow n! pattern: 2, 4, 12, 48 (2!=2, 2!×2=4, 4!×3=12, 12×4=48). First letters increase by 2 (A→D→G→J). Last numbers increase by 2 (11→13→17→23). Only 48J23 satisfies all conditions.

According to the English alphabet, the code of the word BUT is the sum of backward positions of each letter. As, BUT = 25 + 6 + 7 => 38 Similarly, YET = 2 + 22 + 7 => 31 This is the correct answer.

According to the English alphabet, the code of CASK is the sum of one more than the positions of each letter. As, CASK = (3 + 1) + (1 + 1) + (19 + 1) + (11 + 1) => 38 Similarly, CAR = (3 + 1) + (1 + 1) + (18 + 1) => 25 This is the correct answer.

Yes, it is the correct answer. The pattern is a,+2(letter to be typed two times), -1, +1(letter to be typed two times), +2(letter to be typed twice), -1, +1. is followed here. The correct answer comes out to be 'ceg'.
