Question

(i) a = 1, an = an-1 + 2,n> 2 find first five terms​

Answer 1

Answer:

Here a1 = 1

Substituting n = 2, we obtain a2 = a1 + 2 = 1 + 2 = 3

Substituting n = 3, 4 and 5

, we obtain respectively a3 = a2 + 2 = 3 + 2 = 5

a4 = a3 + 2 = 5 + 2 = 7 a5 = a4 + 2 = 7 + 2 = 9

Thus, the first five terms are 1, 3, 5, ,7

Answer 2

Answer:

SO HERE IS YOUR ANSWER

Step-by-step explanation:

GIVEN

a = 1 (First term)

an = an - 1

Also it's Given that n> 2

Therefore..

puting n = 3

a2 = a + 2

= (1) + 2

= 1 + 2

= 3

similarly for each value we get

a4 = 5

a5 = 7

a6 = 9

So FIRST FIVE TERMS ARE..

1, 3 , 5 ,7 , 9
