What Is The Correct Answer class=

Sagot :

The answer is 328.
85 - 40 = 45
148 - 85 = 63
229 - 148 = 81

As seen above, the difference between the numbers are by 18. Therefore,
81 + 18 = 99

So that,
229 + 99 = 328

Therefore, 5+6+7 = 328
The pattern:  Square of the sum + 4.

1 + 2 + 3 ⇒ (6)² + 4 = 36 + 4 = 40
2 + 3 + 4 ⇒ (9)² + 4 = 81 + 4 = 85
3 + 4 + 5 ⇒ (12)² + 4 = 144 + 4 = 148
4 + 5 + 6 ⇒ (15)³ + 4 = 225 + 4 = 229

Therefore:
5 + 6 + 7 ⇒ (18)² + 4 = 324 + 4 = 328

(Note:  It does not take a genius to solve this. Some people can recognize patterns.)
