Question

18th term of AP root 2, 3 root 2, 5 root 2 as soon​

Answer 1

Answer:

35√2

Step-by-step explanation:

√2,3√2,5√2.....

a=√2

d=3√2-√2

  =2√2

nth term= a+(n-1)d

18th term=√2+(18-1)2√2

                =√2+17(2√2)

                =√2+34√2

                =35√2

Answer 2

Answer:

.P is known for Arithmetic Progression whose common difference = an – an-1 where n > 0

Common difference, d

To find 18th term of A.P, firstly find an

We know, an = a + (n-1) d where a is a first term or a1 and d is common difference

When n = 18:

Hence, 18th term of A.P. is 34√2

hope helps

good luck...
