PROBLEM: One term of the arithmetic sequence is a10=32.The common difference is 3.
a) Find the first term
-----------------------------------------------------------------------
To find the first term of arithmetic sequence,use the formula an= a1 + (n-1)d
SOLVE FOR a1:
; an= a1 + (n-1)d
;a10=32 , d=3(the common difference)
;a10=a1 + (10-1)3
;a1=a10 - 27
=32-27
=5
thus,the one first term is a1= 5
