Answer:
7, 8, 9, 10
Step-by-step explanation:
If Zoe worked 4 hours of babysitting at $7 per hour, she earned $28. Therefore, she must earn another $102 to earn at least $130. At $15 per hour, she must work a minimum of 7 hours clearing tables to make at least $102. This is fine since she can work another 10 hours before reaching her maximum of 14 total hours. Therefore, all possible values for the number of whole hours clearing tables that she must work to meet her requirements are 7, 8, 9, 10.
Answer:
1,3,6,10,15,21,…..
These are all the sum of natural numbers upto the n
So, in this series
1st Term = 1
2nd Term = 1+2 = 3
3rd Term = 1+2+3 = 6
4th Term = 1+2+3+4 = 10
So,
Term - n = 1+2+3+….+n = n(n+1)/2
That’s your answer n(n+1)/2
Good Luck
