Series is
Odd position number is addition of 4 in previous odd positioned number
Even placed number is addition of 1 in previous number
3, 4, 7, 8, 11, 12, 15, 16, 19, 20
This is the series of squares and cubes of non-negative integers. 0 squared, 0 cubed, 1 squared, 1 cubed, 2 squared, 2 cubed, etc. So the next number in the series is 4 cubed, or 64.
13112221. Each number describes the previous number. Starting with 1, the second line describes it 11 (one 1). Then the third line describes 11 as 21 (two 1's). Then the fourth line describes 21 as 1211 (one 2, one 1). This is the pattern.
"Samosa King" food delivery sells samsoas in orders of six, nine, and twenty.
What is the largest number of samosa's you cannot order from "Samosa King"?
Since you can buy 6 and 9, you can buy any number divisible by 3 except for 3 itself.
Let's look at numbers over 40. If a number is over 40 is not divisible by 3, you can get a number divisible by 3 by subtracting either 20 or 40.
For 43, you may subtract 40 to get the number 3. But you cannot buy packs if 3, you can only get greater multiples of 3.
For all numbers greater than 43, the number will be divisible by 3 and greater than three, or you can subtract 20 or 40 and get a number that is divisible by 3 and greater than 3.
So you can create any number greater than 43 with 0, 1 or 2 packs of 20, 0 or 1 packs of 9, and n number of packs of 6, where n can be any integer.
