Answer 1

(5) Require to determine whether the given sequence: 6.1,7.0,7.9,8.8,9.7, is arithmetic. That is 4 a 6.1,2 7.0, 7.9,4 8.8,4 9.7,... Now from the given sequence we observe that the first term a 6.1 And 2-47.0-6.1 = 0.9 z-t7.9-7.0 = 0.9 t4-8.8-7.9= 0.9 ts-9.7-8.8= 0.9 So, common difference d 0.9 Therefore, the given sequence is arithmetic
