The domain for N is All integers where n ≥ 1
<u>Solution:</u>
According to statement a1 = 2 and r = 4. This shows that r is greater than 1.
If r is greater than 1 than it includes integers greater than 1 or equal to 1. It does not include all the real numbers because real numbers include negative numbers also.
If starting value is 2, if we put n=0, then we get 2, but if we put a negative value than we would get a number which is not a part of our sequence.
Thus the domain of n is All integers where n greater than or equal to 1

Equivalent expression without fraction
To do this, we simply multiply through by a common multiple of the denominators in the expression.
The denominators are 2 and 3


So, 6 is the least common multiple.
Multiply both sides by 6




<em>Hence, an equivalent expression.</em>
That look hard what subject is it
Answer:
Ishaan is now 6.
Step-by-step explanation:
If Ben is 12 years older, and you have the info that <em>three</em> years ago, he was <em>4 </em>times as old, then all you have to do is divide 12 by 4, giving you 3. You add 3 to that because it's been three years. You have your answer of 6.
Hope this helps! :)
