Answer:
35 - 20n
Step-by-step explanation:
Use destributive property.
5 * 7 = 35
5 * 4n = 20n
35 - 20n

Answer:

Step-by-step explanation:
Given series is,
50,80,110....
First term, a = 50
Common difference, d = 80-50 = 30
We need to find the nth term of the given sequence.
The nth term of an AP is given by :

Put a = 50 and d = 30 in the above formula

Hence, the nth term of the sequence is
.
The expanded form of 584 is:
584 = 500 + 80 + 4
Therefore:
3 · 584 = 3 · ( 500 + 80 + 4 )
Then we will use Distributive property : we can multiply a sum by muptiplying each addend separately and then add the products.
3 · 500 + 3 · 80 + 3 · 4 = 1,500 + 240 + 12 = 1,752
Finally: 3 · 584 = 1,752.
