What is the sum of all prime numbers beetween 70 to 80? What is the product of prime numbers immediately before and after 50?

Answer both plz thx

Prime numbers between 70 and 80 are 71,73,79

71+73+79=223

50 =2x5x5=2x5^2

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
