Tan y = (p+1)/(p-1) where p is a constant greater than 1 work out an expression for sin y give your answer in form (ap+b)/(root (cp^2 +d) ) you may use a diagram

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

what i would say the best answer is a. 40.5
