Do you know your Prime numbers, Square numbers, etc? If so, have a go. If not, ‘Google’ them and then have a go!
Add together the 7th Prime number, the 7th Square number, the 7th 2-digit number and the 7th whole number that contains a ’7′. What is your answer?
Answer is 139 (17+49+16+67)
You found the correct four answers but added them up incorrectly!!
Surely that’s 149?
It sure is Catherine, the four answers of 17+49+16+67 make 149
