My mistake, 27, 18, 12, 8, 16/3, 32/9, 64/27, 128/81...it's the 8th term.

For the 2nd question, the smallest term will be 78125/729 or the 8th term if i'm right.

I got 8 for both questions

erm..wait ya..tis ques..just now that noe to do d..

find the number of multiples of 7 between 150 and 450..how to do tis type?

154, 161...., 448.
Identify the progression and find the nth term = 448.

how to get that?

a = 154
d = 7
Use the formula to find the terms (I forgot, sorry!)
T_n = 448
Find n.

Number of mutiples of 7 = 43?

ya..how to do.. how u get the series?

somehow i feel abit lazy to study today maybe because i study too much in the past few week which make me really stress.

LOL ... I really don't think it's a good idea to ask like this .. but ... whatever.

oh..i know d..izzit we think two multiple of 7 that more than 150 and then think the last one too?

Learn from Vick, he is only Form 4 but already study Form 5 subjects. You better hurry up!

Since they want multiples of 7 the number after 150 is 154 (multiple 7)
The number right before 450 which is also a multiple of 7 is 448.
So a = 154, d = 7
Tn = 448
448 = a + (n-1)d
448 = 154 + 7n - 7
7n = 301
n = 43

oh..so sendiri must create the series la?

Here's an interesting question.
For the following data set (in ascending order):
a, 6, 7, 7, b, c, 11, 12, 13, d, 17, 18

The mean is 10.75;
The range is 13;
The median is 10;
The interquartile range is 7.

Find the values of a, b, c and d.

Vick.... i have a task for you. Re-read all your form 4 chapters. Everything you don't understand. Just assume its from Form 5, and you have a long way to go. And, go read ALL THE STORY BOOKS from d store. U sure can pass ur time one. =D

cant la..getting to love add math

Okay..... go to the nearest bookstore. =D

i got form 5 books d..i bought SPM one..

You are posting about this for the fourth time. And massive use of Caps. O.o
