Question

Please help! ):

Answer 1

well using the 1st term

1/5 you need to multiply it by 2/3 to get the 2nd term 2/15

then check the 3rd term

2/15 * 2/3 = 4/45

so check you are doubling the numerator and tripling the denominator

if its yes in each case the sequence is geometric with a common ratio of 2/3
