iragen [17]
Cost of material  labour & overheads is in the ratio 0f  3:4:5
if cost of material  =  33.60
cost of labour  =      4/3* 33.60  =   44.8
cost of material   =      5/3 * 33.60  =  56
cost of article =  33.60+ 44-8 + 56 =  134.4

What is the sum of the arithmetic sequence 3, 9, 15..., if there are 24 terms? (5 points)
Vinil7 [7]

There's a fixed difference of 6 between terms (9 - 3 = 6, 15 - 9 = 6, and so on). The first term of the sequence is 3, so the n-th term is

3 + 6(n-1) = 6n - 3

If there are 24 terms in the sum, then the last term is 6×23 - 3 = 135.

Let S be the sum,

S = 3 + 9 + 15 + \cdots + 123 + 129 + 135

Reverse the order of terms:

S = 135 + 129 + 123 + \cdots + 15 + 9 + 3

If we add up the terms in the same positions, we get twice S on the left side, while on the right side we observe that each pair of terms will sum to 138.

S + S = (3 + 135) + (9 + 129) + (15 + 123) + \cdots + (135 + 3)

2S = 138 + 138 + 138 + \cdots + 138

and since there are 24 terms in the sum, the right side is the sum of 24 copies of 138. In other words,

2S = 24 \times 138

and solving for S gives

S = \dfrac{24\times138}2 = \boxed{1656}
