Find the nth term of this number sequence
1,7,13,

The nth term of the sequence is

Step-by-step explanation:

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

U(n) = a + ( n - 1)d

where n is the number of terms

d is the common difference

a is the first term

From the question

a = 1

d = 7 - 1 = 6

U(n) = 1 + ( n - 1)6

= 1 + 6n - 6

The final answer is

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
