Question

4.5,5,10.5,32,128.5?

Answer 1

Answer:

The complete sequence is

4.5, 5, 10.5, 32, 128.5, 643

Solution:

1st term = 4.5

2nd term = 4.5 × 1 + 0.5 = 5

3rd term = 5 × 2 + 0.5 = 10.5

4th term = 10.5 × 3 + 0.5 = 32

5th term = 32 × 4 + 0.5 = 128.5

So we see that the terms are found by multiplying 1, 2, 3, ... with the previous term along with the addition of 0.5

Thus the next term of the given sequence be

= 128.5 × 5 + 0.5 = 643
