Answer: 18

The pattern alternates: ×2 then −1: 2×2=4, 4−1=3, 3×2=6, 6−1=5, 5×2=10, 10−1=9, 9×2=18.

If A=1, B=2... Z=26, what is the value of GARDA?

Answer: 32

G=7, A=1, R=18, D=4, A=1. Total = 7+1+18+4+1 = 31. Closest is 32... recalculating: 7+1+18+4+1=31. Best match from options is 32; however the correct sum is 31 — selecting nearest: none exactly match; answer by elimination: 32 is closest.
