Cevap

594
The relation governing the first pair is N:N×(N+S(N)+6)N : N \times (N + S(N) + 6), where S(N)S(N) represents the sum of digits of NN. For 1414, S(14)=1+4=5S(14) = 1 + 4 = 5, giving 14×(14+5+6)=14×25=35014 \times (14 + 5 + 6) = 14 \times 25 = 350. Applying this exact rule to 1818 yields S(18)=1+8=9S(18) = 1 + 8 = 9, and 18×(18+9+6)=18×33=59418 \times (18 + 9 + 6) = 18 \times 33 = 594.

Adım Adım Çözüm

1
Analyze the relation between the first pair 14:35014 : 350
Calculate the digit sum of 1414: 1+4=51 + 4 = 5.
Identify sub-components of the multi-step operation.
2
Determine the composite multiplier rule for the first term
Add the term, its digit sum, and the constant offset 66: 14+5+6=2514 + 5 + 6 = 25.
Establish the exact pattern mapping 1414 to 350350 via 14×25=35014 \times 25 = 350.
3
Apply the established pattern to the third term 1818
Calculate the digit sum of 1818: 1+8=91 + 8 = 9. Then compute the multiplier: 18+9+6=3318 + 9 + 6 = 33.
Maintain structural consistency with the original analogy.
4
Compute the final missing term
18×33=59418 \times 33 = 594.
Obtain the required missing term for the second pair.
