3 answers

The sequence has been formed by multiplying each term by the counting number at which it appears.

So,

the 5th term would be 5 x 4.5 = 22.5,

the 6th term would be 6 x 5.5 = 33,

the 7th term would be 7 x 5.6 = 39.2

and the next two terms would be 8 x 6.7 = 53.6 and 9 x 7.8 = 70.2.

Therefore, the answer is 5.6, 6.7.
