Answer:
6 1.5/4
Step-by-step explanation:
-43/204
Step-by-step explanation:
−5/12 × 17/17 + 7/34 × 6/6 =
= −85/204 + 42/204
= −85 + 42/204
= −43/204
$2,812 will be the final value of the account
See how the arithmetic sequence is made:
5, 5+4=9, 9+4=13, 13+4=17, ...
So the 21th term will be:
5( first term)+20( n-1 term)•4= 85
And the sum of the first 21 is :
21(5+85)/2= 21•45= 945
