given,
1st term(a)= -2
2nd term (t2) =-12
3rd term (t3) =-60
4th term(t4)= -120
here common ratio (r)=t2/t1=t4/t3
or, -12/-2= -120/-60
or,6=2
hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.

The concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.
<h3>What is pH value?</h3>
The pH value shows that how much a solution is acidic or basic. The range of the pH value lies between the 0-14.
The pH value can be calculated with the following formula.
![\rm pH=log[H^{+}]](https://tex.z-dn.net/?f=%5Crm%20pH%3Dlog%5BH%5E%7B%2B%7D%5D)
Here, [H⁺] is the molar hydrogen ion concentration.
The pH of lemon juice at 298 K is found to be 2. 32. Put this value of pH in the above formula as,
![\rm 2.32=log[H^{+}]\\\ [H^{+}]=4.79\times10^{-3} \rm \; M](https://tex.z-dn.net/?f=%5Crm%202.32%3Dlog%5BH%5E%7B%2B%7D%5D%5C%5C%5C%20%5BH%5E%7B%2B%7D%5D%3D4.79%5Ctimes10%5E%7B-3%7D%20%5Crm%20%5C%3B%20M)
Hence, the concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.

(not sure if I'm right) Using this Formula Part/Whole = %/100
$350/Original Price = 10%/100
cross multiply
10w = 35,000
divide by 10 on both sides
W = $3,500
(seems real high so I'm not sure)
