Answer 2

Given :-

• tn = 2n - 5

To find :-

• first two terms of sequence . ?

Solution :-

we have,

→ tn = 2n - 5

putting n = 1 , we get,

→ t1 = 2 * 1 - 5

→ t1 = 2 - 5

→ t1 = (-3) (Ans.) = First term .

and, putting n = 2 , we get,

→ t2 = 2 * 2 - 5

→ t2 = 4 - 5

→ t2 = (-1) (Ans.) = second term .

therefore, first two terms of sequence are (-3) and (-1) .
