Answer:
78 x 10² or 7.8 x 10³
Step-by-step explanation:
you have to get the exponents the same before you can subtract the coefficients
8 x 10³ = 80 x 10²
80 x 10² - 1.7 x 10² = 78 x 10² or 7.8 x 10³
Given:
The nth term of a number sequence is
.
To find:
The first 3 terms and the 10th term.
Solution:
We have, nth term of a number sequence.

For n=1,



For n=2,



For n=3,



For n=10,



Therefore, the first three terms are 3, 8 and 15 respectively. The 10th term is 120.
