Find the sum of the first 60 terms of the sequence below a_n=5n+10
ASHA 777 [7]
 \displaystyle{a_n=5n+10

means that the value of the n'th term of the sequence is 5n+10

for example, the value of the seventh term is  \displaystyle{a_7=5\cdot 7+10=35+10=45


The sum of the first 60 terms can be calculated as follows:

\displaystyle{ a_1+a_2+a_3+...+a_{60}= 

\displaystyle{ (5\cdot1+10)+(5\cdot2+10)+(5\cdot3+10)+...(5\cdot60+10)

=5(1+2+3+...59+60)+10\cdot 60


using the Gauss formula for the addition of the first n natural numbers:

1+2+3+...59+60= \frac{60\cdot(61)}{2}=30\cdot61=1,830


thus we have:

5(1+2+3+...59+60)+10\cdot 60=5\cdot1,830+600

=9,150+600=9,750


Answer: 9,750
