7• Let 1st no. = x

2nd no. = x + 2 (since they are consecutive ODD no.s, we will add 2)

3rd no. = x + 2 + 2

= x + 4

According to the question:

x + x + 2 + x + 4 = 69

= x + x + x + 2 + 4 = 69

= 3x + 6 = 69

= 3x = 69 - 6

= 3x = 63

= x = 63/3

= x = 21

Numbers= 21, 23 and 25

Since 23 is a prime number, it will be the answer
