Answer:
The number of apple for 1 cup of water is 1.5 apples
Step-by-step explanation:
Given as :
The number of cups of water = 91 cups
The number of apples for every 91 cups of water = 140
Let The number of apple for 1 cup of water = n
<u>Now, From unitary method :</u>
∵ For every 91 cups of water , the number of apple needed = 140
∴ For every 1 cup of water , the number of apple needed = 
I.e n = 
or, n = 1.5 apples
The number of apple for 1 cup of water = n = 1.5 apples
Hence The number of apple for 1 cup of water is 1.5 apples Answer

Answer:
<u>The sequence is</u>
- 1, 1 + 2, 1 + 2 + 3, 1 + 2 + 3 + 4, ...
Each term is the sum of the consecutive numbers from 1 to that number.
<u>The nth term is the sum of the first n numbers:</u>
- aₙ = 1 + 2 + 3 + ... + n
- aₙ = 1/2n(1 + n) (formula for sum of the n terms of arithmetic progression with the first term of 1 and common difference of 1)
- aₙ = n(n + 1)/2
1) The number of circles in the nth pile is n(n + 1)/2
2) When n tends to infinity the number of circles tends to infinity
