Sequence 2

Write the first 5 members of an arithmetic sequence a11=-14, d=-1

Result

a1 =  -4
a2 =  -5
a3 =  -6
a4 =  -7
a5 =  -8

Solution:

a1=−14−(11−1)⋅(−1)=−4a_1 = -14 - (11-1)\cdot (-1) = -4
a2=a1−1=−5a_2 = a_1 -1 = -5
a3=a2−1=−6a_3 = a_2 -1 = -6
a4=a3−1=−7a_4 = a_3 -1 = -7
a5=a4−1=−8a_5 = a_4 -1 = -8
