Question

the sum of four conseutive multiples of 5 is 330

Answer 1

Hi...☺

Here is your answer...✌

Let the three consecutive multiples of 5 be x,x+5,x+10

ATQ,

x+x+5+x+10 = 330

3x+15 = 330

3x = 330-15

3x = 315

x = 315/3

x = 35

Hence the consecutive multiples are 35,40,45

Thank you ⭐

Answer 2

the series will be in arithmetic progression whose sum S=n/2(2a+(n-1)d)
n=no. of terms
a= initial term
d=common difference
putting these values , we get
330=4/2(2a+(4-1)×5)
165=2a+15
75=a
