7 is to 34 as 5 is to?

In a number-based analogy of the form “a is to b as c is to ?”, the two numbers in the given pair are connected by ONE fixed arithmetic rule — usually a single multiplication (or division) combined with a single addition or subtraction. Finding that exact rule from the given pair and reapplying it unchanged to the third number gives the missing term.

1. Test a multiplicative link first: 7 × 5 = 35, which is only 1 away from the given second term, 34.

2. Refine the rule to (n × 5) − 1 and verify it on the given pair: 7 × 5 − 1 = 35 − 1 = 34 — an exact match with no rounding.

3. Apply the identical rule, (n × 5) − 1, to the third number, 5: 5 × 5 = 25, then 25 − 1 = 24.

Other single-step rules can also reproduce 7 → 34 — for example, (n × 4) + 6 gives 34 as well — but applying that same rule to 5 gives 26, which is not among the four offered numbers. The rule (n × 5) − 1 is the one that, applied to 5, lands exactly on an offered option — 24 — making it the best-supported choice among the given options.

So 5 is to 24.
