The explicit formula for calculating the sum is

The sum of the nth term of a sequence is expressed as;

a is the first term
d is the common difference
n is the number of terms
For the sequence 0 + 1 + 2 + 3 +...

Similarly for the sequence:
1 + 2+ 3 + 4+...

Answer:
That would be 5 possibilities (or 5 events for position 1).
Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20
