Question

How many multiples of 4 lie between 10 and 205​

Answer 1

let the number of multiples be n

here,

the first term= 12

and the common difference be = 4.

also,

the last term= tn= 204

now,

by the formula,

tn=a+(n-1) ×d

204= 12+(n-1) ×4

204= 12+ 4n-4

204= 12-4+4n

204= 8+4n

204-8= 4n

196= 4n

196/4= n

49= n

hence,

there are 49 multiples of 4 between 10 and 205

hope this helps!!✌☺❤
