Question

Ho2 do you find the first five terms of the arithmetic sequence given `a_1=5/8` and d=3/8?

Answer 1

First five terms are `5/8,1, 1 3/8 , 1 3/4 and 2 1/8`

Explanation:

`a_n=a_1+(n-1)d`

`a_1=5/8 , a_2=5/8+3/8 =8/8=1 , a_3=5/8+2*3/8 =11/8=1 3/8`

`a_3=5/8+3*3/8 =14/8=1 3/4 , a_3=5/8+4*3/8 =17/8=2 1/8`

First five terms are `5/8, 1, 1 3/8 , 1 3/4 and 2 1/8` [Ans]
