How do you know if a problem is an arithmetic equation?
Ans: You have a pattern in your sequence.
ex :- 1,2,3,4,5,6,
Answer:
9000000+400000+50000+2000+700+20+9
Let assume two consecutive odd numbers 2x+1 and 2x+3
It is given their sum is 52.
So we can write equation as


On subtraction 4 on both sides of equation



x = 12
So the numbers are
first number is =

Second number is =

So the required numbers are 25 and 27.
The answer would be 399.
First you'd find 5% of 380.
To get a decimal point for 5% you just need to move the percent sign twice to the left.
5% ➡ .05
Now multiply .05 with 380
380 × .05 = 19
Since you're finding the increase of 5% along with 380 you add it together
380 + 19 = 399
