Answer (1)
A. 1. 5 + 9 + 13 + 17 + 21 + 25 + 29 + 33 + 37 + 41 = 2302. -17 + -12 + -7 + -2 + 3 + 8 + 13 + 18 + 23 + 28 = 373. 4 + 9 + 14 + 19 + 24 + 29 + 34 + 39 + 44 + 49 = 2214. -16 + -20 + -24 + -28 + -32 + -36 + -40 + -44 + -48 + -52 = -340B. 1. 3 + 11 + 19 + 27 + 35 + 43 + 51 + 59 + 67 + 75 + 83 + 91 = 5642. 9 + 12 + 15 + 18 + 21 + 24 + 27 + 30 + 33 + 36 + 39 + 42 + 45 + 48 + 51 + 54 + 57 + 60 + 63 + 66 + 69 + 72 + 75 + 78 + 81 + 84 + 87 + 90 + 93 + 93 = 1, 572Are you sure na the number 2 ang Sn ay 1, 575?
