Given:
1,5,25,61.....
To find:
The following number.
Solution:
We can see a pattern in the given sequence.




Using this pattern the next term is the sum of squares of 7 and 8.

Therefore, the next number is 113.
Step-by-step explanation:
3x x 10 = 22
3x x 10 - 10 = 22 - 10
3x = 12
3x ÷ 3 = 12 ÷ 3
x = 4
5x + 8
5(4) + 8
20 + 8
28
Answer: N= -1
Explanation:
N-11 =3n - 1-8
First, Add the 1-8 so it’s now n-11 =3n -9
Next, collect like terms so now it’s is -2n=-9+11
Lastly, divide both sides by -2 which will leave you with n=-1
