6 0

In the sequence, we are given with -2, 8, -32...This is a geometric type of sequence with a geometric ratio of 4. a1 is equal to -2 and r is equal to 4The expression is
a n = a1 * r ^ (n-1) where n is an integer ora n = a1 * (-4) ^ (n-1)we can check or verify this using the given

There are 44 total small egg cartons, 264 / 6 = 44

There are 176 total medium egg cartons, (264 / 3) x 2 = 176

There are 44 total big egg cartons, 176 + 44 = 220

264 - 220 = 44

<u>Note: (So you don't get confused) Above is just the number of egg cartons, below is the number of eggs.</u>

There is a total of 352 eggs in the small egg cartons, 44 x 8 = 352

There is a total of 2112 eggs in the medium egg cartons, 176 x 12 = 2112

There is a total of 792 eggs in the large egg cartons, 44 x 18 = 792

Hope this Helps! :)
