0 jane has a swimming pool which is shown in the
liagram. She wants to put a coloured lining on the
ottom. A roll of blue lining costs £4 per square
netre. A roll of purple lining is on offer for £3.50 per
quare metre. How much will she save by using the
urple lining rather than the blue lining?​

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

so, converting firstly the mixed fractions to improper fractions and then "adding".

the correct answers i think are b. and d.

give me brainliest if it is correct!

probably .5

i can on others if necessary.
