Step-by-step explanation:
An arithmetic sequence is a sequence that has the property that the difference between any two consecutive terms is a constant. This constant is called the common difference. If a1 is the first term of an arithmetic sequence and d is the common difference, the sequence will be: {an}={a1,a1+d,a1+2d,a1+3d,…}
Answer:
a7=a+(7-1)d = a + 6d
a27=a + ( 27 - 1 ) = a + 26d
since, a27 - a7 = 84
a+ 26d - a - 6d = 84
d=4.2
