50 birds peck grain. The first bird pecked 40 granules; the second bird pecked 60 granules; and each of the following birds pecked the mean of the granules that were pecked by all the previous birdies. How many granules did the 50th bird peck?

50.

Step-by-step explanation:

As you can see the third bird pecks 60 + 40 /2 = 50 granules. The fourth bird thus pecks 60 + 40 + 50 /3 = 50 granules. The fifth bird pecks 60 + 50 + 50 + 40/4 = 50 granules. As you can see, it will always be 50 after this.

hows it hangin lol

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
