Step-by-step explanation:
basta yan Yung answer
26=a1+d(5-1)
26=a1+4d
EQ2: a12=a1+d(n-1)
47=a1+d(12-1)
47=a1+11d
To find d:
47=a1+11d - 26=a1+4d
ANSWER: 21=7d (divide both with 7 to eliminate (7)d, so d=3
To find the 1st term(a1):
Use EQ1
26=a1+4d
26=a1+4(3)
26=a1+12 (transfer 12 to 26 then subtract)
a1=14
