Some people take the early retirement option at age 62. According to the Social Security Administration, if you retire at age 62
Vera_Pavlovna [14]

Answer:

$3900.

Step-by-step explanation:

If retirement is taken at the age of 67 years, income  = $1300 per month.

% Loss, if retirement taken at the age of 62 years = 25% per month

Loss in dollars per month if retirement taken at the age of 62 years = 25% of Monthly income if retirement is taken at the age of 67 years

\Rightarrow \dfrac{25}{100} \times 1300\\\Rightarrow \dfrac{1300}{4}\\\Rightarrow 325 \$

We know that there are 12 months in an year.

So, annual loss in total annual income over one year:

Loss in dollars per month \times 12 :

325 \times 12 = <em>3900$</em>

Find the 3rd term of an arithmetic sequence with t2= 9/2 and t5= 6
qwelly [4]
<span>Well a simply way is to look at the problem as

Term 1 | 2 | 3 | 4 | 5 ----------------------------
Value | 9/2 | | | 6

There are 3 terms from 2 to 5 and the value increases 6 - 9/2 = 3/2 so the common difference is 3/2 divided by 3 so the common difference is 1/2 so to find the 3rd term add 1/2 to the 2nd term the pattern is each term is increasing by 1/2.. or 1/2 is added to the previous term. </span>
