Answer:
144.
Step-by-step explanation:
Sum of n terms = (n/2)[a1 + l] where a1 = first and l = last term.
There are ( 1 + 23) / 2 = 12 terms in this series.
So the sum = (12/2) [ 1 + 23]
= 6 * 24
= 144.
1/620 is the simplest form of 2/1240
all you had to do was simplify
2 divided by 2=1
1240 divided by 2=620 <span />
