Answer:
<h3>
1200 and 14400</h3>
Step-by-step explanation:
n - smaller number
The larger number is 12 times the smaller number
12n - larger number
n + 12n = 13n - the sum of these numbers
13n = 15600
÷13 ÷13
n = 1200
12n = 12•1200 = 14400
Check: 14400+1200 = 15600
Answer:
i think its c
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
First term a1 = 13
11th term a11 = a1 + 10d = 83
So a1 + 10d - a1 = 83 - 13
10d = 70
d = 10
The common difference d = 7.
Sum of n terms = (n/2)[2a1 + (n - 1)d]
Sum of the first 20 terms:
S20 = (20/2)[2*13 + (20-1)7]
S20 = 10 *(26 + 19*7)
S20 = 10*159 = 1590.
