Question

If 5 @ 1 = 26,3 @ 4 = 13, then 6 @ 2 = ?

• A. 36
• B. 38
• C. 40
• D. 42

Answer 1

Answer:

B. 38

Let's find the pattern:

Given:

• (5 @ 1 = 26)

• (3 @ 4 = 13)

Notice:

$5^2 + 1 = 25 + 1 = 26$
$3^2 + 4 = 9 + 4 = 13$

So the operation appears to be:

$a @ b = a^2 + b$

Now apply it:

$6 @ 2 = 6^2 + 2 = 36 + 2 = 38$

Answer: 38
