Question

7, 29, 51………. Can 685 be a word in the parallel series?​

Answer 1

Step-by-step explanation:

the list of ap is 7, 29, 51

a=7, d=22

an = 685

using an formula= a+(n-1)d.

685= 7+(n-1)22

685-7= 22n-22

678+22 =22n

700/22=n

350/11 =n so it is not ending and have no appreciate ending .

so 685 is not a word in parallel series.
