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\"?

Yeah, one of my son's current classmates in Sec 1, left singapore after p5, went to Australia for his p6 year, skipped psle as such, came back in Dec/Jan this year (the sec 1 year), took the school's entrance exam and gained admission and joined the school late - maybe in late Jan or Feb.. But well, this boy is not coping all that well actually.[quote]
I am actually a returning Singaporean. Coincidentally, when I migrated, I migrated to Australia too. When we left my elder brother was also in p5. We returned to sg in dec 2009. So he skipped PSLE. When he continued his studies in 2010 he was in sec 2. He took entrance test and managed to qualify for express. It was quite impressive considering that we stayed in Aust for 2-3 yearsand the primary school standard in West. Aust was much slower compared to Singapore.

But its hard on him too...

[/quote][/quote]Wah, you dig out such an old comment? Actually that boy who joined the school in sec 1 (w/o psle), didn't make it in the end. His full-year GPA was way way too low. So he had to leave the school.

[quote=\"Brenda10\"]Hi Tinkerbelle,


Same here to DD. Only homework for this long weekend are one set of science and CL papers. No sign of EL and Maths! Lucky we bought the 2011 papers ourselves!

Hi Brenda,
I totally agree with you.....lucky we bought the 2011 prelim papers. Dunno why the sch suddenly very laid back

On second thoughts, maybe the schs know parents will buy prelim papers so they ease off a bit. DD set a target to finish the prelim papers by this weekend. Hopefully can achieve that. How's your DD's progress? Nearly finish all the prelim papers?

Hi Tinkerbelle,

Possible.

We slow down in Maths and science and do some EL and CL papers. [/quote]Hi Brenda,
DD is alternating all her subjects too. Need a break from maths & science.
