Answer:
51
Step-by-step explanation:
when n=1
<h2><u><em>t 1=1 </em></u></h2>
<u><em>when n=2</em></u>
<u><em>t2=4</em></u>
<u><em>as first term is 1 and second term is 4 so the common difference is 3 ,for 6 term if you put this in formula for sum to the n term you will get 51 </em></u>
<u><em>t1 =1</em></u>
<u><em>d=3</em></u>
<u><em>n=6 </em></u>
<u><em>than S6=51 </em></u>

Answer:
£62.4
Step-by-step explanation:
There are 104 coins in a bottle 1/2 of the coins are £1 coins
Hence:
1/2 × 104 coins = 52 coins
Since 1/2 of the coins are £1 coins
Hence
52 coins = £52
The remaining the rest of the coins are 20p coins
The rest = 1/2 of 104 coins = 52 coins
Note that:
100 pence = 1£
Hence:
100p = 1 £
20p = x
Cross Multiply
100p × x = 20p × £1
x = 20p × £1 /100p
x = £0.2
So, one 20p coin = £ 0.2
Hence:
one 20p coin = £ 0.2
52 20p coins = x
Cross Multiply
x = 52 × £0.2
x = £10.4
The total value for the 104 coins is
= £52 + £10.4
= £62.4
1/5 < 3/10 < 1/2 i believe thats it i hope this helped:)
