Paul was going to sell all of his stamp collection (s) to buy a video game. After selling half of them he changed his mind. He then bought ten more. How many did he start with if he now has 22?

Paul had 24

Step-by-step explanation:

He has 22 now. Subtract the 10 he just bought for 12, which was half of his original collection.

22-10=12

12×2=24

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
