Question

how many multiples of 4 lie between 10 and 250.​

Answer 1

a=12

n=?

d=4

An=248

An=a+(n-1)d

248=12+(n-1)4

248=12+4n-4

248=8+4n

248-8=4n

240=4n

n=240/4

n=60

Hence, number of multiples of 4 which lie between 10&250 are 60.

Answer 2

Step-by-step explanation:

a=12

an=248

d=4

n=?

• an=a+(n-1)d
• 248=12+(n-1)4
• (n-1)4=248-12
• (n-1)4=236
• n-1=236/4
• n-1=59
• n=59+1
• n=60

there for 60 number of multiples of 4 lie between 10 and 250
