D is left of A, A is left of B, C is right of B. So order is D-A-B-C

Perfect squares: 1², 2², 3², 4², 5², 6², 7² = 49

Each letter is shifted by 1 position forward in alphabet. F→G, A→B, T→U, H→I, E→F, R→S

From constraints: R is immediately right of Q, T is rightmost, S is left of R. So: S-P-Q-R-T satisfies all conditions

Differences are: 6, 8, 10, 12, and next difference is 14. So 41 + 14 = 55

These are perfect squares: 11², 12², 13², 14², 15², 16², 17². Next is 17² = 289

Some birds are colorful and all birds can fly, therefore some colorful things can fly

Fibonacci series where each number is sum of previous two: 13 + 21 = 34

Some athletes are students, and all students are learners, therefore some athletes are learners

Each letter coded as its position in alphabet: M=13, U=21, S=19, I=9, C=3
