OG 12 Prob 85
In an increasing sequence of 10 consecutive integers , the sum of 5 integers is 560.what is the. sum of last 5 intergers in the sequence?
A)585
B)580
C)575
D)570
E)565
The solution is given as x+x+1+x+2+x+3+x+4=560
My doubt is consecutive integers can be defined as x,x+d,x+2d,x+3d
where d is the difference.
But here it mentioned the consecutive integers with diff 1 like(1,2,3,4)But the difference can be anything like 2or 3 also
Is it correct?Please clarify
