Please solve this question i need help​

4c/2a 60 degrees 3bf 2ad

f=120

b=40

d=140

e=120

c=30

a=30

answer: 2 and 1

step-by-step explanation: got this question

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
