Graph the first six terms of a sequence where a1 = 3 and d = -10.
To determine the first six terms of the arithmetic progression, add the common difference to the prior term
a1 = 3
a2 = 3 + -10 = -7
a3 = -7 + -10 = -17
a4 = -17 + - 10 = -27
a5 = -27 + -10 = -37
a6 = - 37 + -10 = -47
Plot these values in the number line.
Answer:
3, -7, -17, -27, -37, -47
Step-by-step explanation:
Given: First term: a= 3 and Common Difference, d = -10
We need to find the first six term of the sequence.
Formula: \(a_n=a+(n-1)d\)
where,
\(a_n\) nth term of series
a is first term
n is number of term
d is common difference
For Second term, n=2
\(a_2=3+(2-1)(-10) = 3-10=-7\)
For Third term, n=3
\(a_3=3+(3-1)(-10) = 3-20=-17\)
For Fourth term, n=4
\(a_4=3+(4-1)(-10) = 3-30=-27\)
For Fifth term, n=5
\(a_5=3+(5-1)(-10) = 3-40=-37\)
For Sixth term, n=6
\(a_6=3+(6-1)(-10) = 3-50=-47\)
Hence, The sequence is 3, -7, -17, -27, -37, -47
