The common difference is 6

Step-by-step explanation:

Given sequence is:

7, 13, 19, 25....

The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

$a_1 = 7\\a_2 = 13\\a_3 = 19\\a_4 = 25\\d = a_2-a_1 = 13-7 = 6\\d = a_3 - a_2 = 19-13 = 6\\d = a_4-a_3 = 25-19 = 6$

Hence,

The common difference is 6

How do I solve question 13 and 14?

xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

$a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\$

if counting the sequence from $a_{0}$ then $a_{4}$ is 17, but if

$a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\$

counting from $a_{1}$ , then $a_{4}$ is 13.

14.

$a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28$

qwelly [4]

Answer: 30,000 months or 2,500 years

She'd better start saving more haha.

Step-by-step explanation:

$Goal=4.2x10^6\\Savings/month=1.4x10^2$

$\frac{4.2x10^6}{1.4x10^2} =(\frac{4.2}{1.4})x10^(^6^-^2^)=(3)x10^4=3x10^4 =30000 months=\frac{30000}{12}=2500years$
