Question

How many multiples of 4 are between 5 and 125?

Answer 1

Hey mate here's your ans.

Required A.p will be 8,12,16....124

Given:a=8,d=4,tn=124

To find:n=?

Solution:tn=a+(n-1)d

124=8+(n-1)4

124=8+4n-4

124=4+4n

124-4=4n

120=4n

n=120/4

n=30

Thus there are 30 multiples of 4 between 5 and 125.

Thank you

Answer 2

Answer:

There are 30 multiples of 4 between 5 and 125.

Step-by-step explanation:

Required arithmetic progression will be 8,12,16....124

Given:

a=8, d=4, tn=124

To find: n=?

formula for finding this is:

tn=a+(n-1)d

124=8+(n-1)4

124=8+4n-4

124=4+4n

124-4=4n

120=4n

n=120/4

n=30

Thus there are 30 multiples of 4 between 5 and 125.
