Question

The sum of 4 consecutive odd numbers is 64 find the prime numbers out of these numbers

Answer 1

Answer:

Prime no.s = 13 , 17 , 19

Step-by-step explanation:

let the 1st no. be a

∴2nd no. = a+2

∴3rd no. = a+4

∴4th no. = a+6

ATQ,

a+a+2+a+4+a+6=64

a+a+a+a+2+4+6=64

4(a)+12=64

4(a)=64-12

4(a)=52

a=52/4

a=13

1st no.=13

∴2nd no. = a+2=15

∴3rd no. = a+4=17

∴4th no. = a+6=19

Prime no.s = 13 , 17 , 19
