Row No:


1st 2
2nd 2 4
3rd 2 4 6
4th 2 4 6 8
5th 2 4 6 8 10
. . . . . .
If the sum of numbers in the N row is 10 302, find N.

Formula is Nx(N+1)=sum of numbers in N row.

So.....
Nx(N+1)=10302
101x(101+1)=101x102=10302

Ans: N = 101 when the sum of numbers in the 101 row is 10302.

How can I know n is 101? using \"guess and check\"?

When faced with this question,


Row No:

1st 2
2nd 2 4
3rd 2 4 6
4th 2 4 6 8
5th 2 4 6 8 10
. . . . . .
If the sum of numbers in the N row is 10 302, find N.

How would you solve it?

Thanks for such good info, this decision should take by DS, and I just checked with him. He wants to go to DHS.Actually, his dream school is HCI, but HCI DSA failed, so I advice him to work hard for PSLE.

Hi 1248,
Sorry to hear about your DS's HCI experience. At least you have COs from NUSH & DHS.
Will your DS put DHS at 1st choice or will he try to get into HCI through central posting? All the best to your DS. :rahrah:

Yes, DS selected DHS as 1st choice. However, we'll appeal for his dream sch once his T'score meets the HCI's COP.

I have headache due to DS getting CO from NUSH and DHS,any suggestions? :?

:congrats: and welcome.
One is in the west and one in the east, you must be someone staying in central? These 2 schools are of opposite system, one a SAP school with strong chinese background and a long tradition. The othe is new, modular subject based system with an early emphasis on applied science. For me, I am leaving it to my DS to decide, with us offering guidance. I am still inclined towards the traditional education system, and that will be my guidng principle.

Thank you for your advice.
