[3 3 a) At the start of 2006 Craig owned a stamp collection worth £2500. He expected the value at the
start of each year to increase by 6% by the end of the year. How much did he expect the collection
to be worth at the end of 2008?

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

the answer to your question is minor arc.
