Question 175300
here we have to calculate common difference which means given progression is arthemetic progression.
given first term a1=8
seventeen th term a7=88
 but a17=a1+16d where a1 means first term and d means common difference
 therfore a1+16d=88
        =>8+16d=88
        =>16d=88-8
        =>16d=80
        =>d=80/16
        =>d=5
therfore common difference d is 5.
general term tn=a1+(n-1)d
               =8+(n-1)5
               =8+5n-5
               =5n+3.
and progression is 8,13,18,23,28,------------------
