(tn) is an arithmetic sequence in which t3-t5=6, t4= 16 , find the (n)th term and find the order and the value of the first negative term in this sequence .

Since is arithmetic, it's given recursively by

where is a fixed number and is the starting term in the sequence. We have

and so on, so that

We're told that , so

and

so that

Then the first term in the sequence is :

and the sequence has general formula

The first negative term occurs for

The first negative term in the sequence is .

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

2 2/3 hours duhh silly
