write the first five terms of the arithmetic sequence whose first term is 7, and whose common difference is 6
write the first five terms of the arithmetic sequence whose first term is 7, and whose common difference is 6
Answer
Explanation:
Step1: Identify first - term
The first term (a_1 = 7).
Step2: Find second - term
Use the formula (a_n=a_{n - 1}+d), so (a_2=a_1 + d=7 + 6=13).
Step3: Find third - term
(a_3=a_2 + d=13+6 = 19).
Step4: Find fourth - term
(a_4=a_3 + d=19+6 = 25).
Step5: Find fifth - term
(a_5=a_4 + d=25+6 = 31).
Answer:
The first five terms are 7, 13, 19, 25, 31.
