WebNov 27, 2015 · As the sum of the first ten terms is −35 that gives us 10( a1 + a10 2) = −35 As the tenth term is 10 that gives us 10( a1 +10 2) = −35 ⇒ a1 +10 = −7 ⇒ a1 = −17 Which gives us the first term as −17. To find the difference, we note that 10 = a10 = a1 + 9d = − 17 +9d ⇒ 9d = 27 ⇒ d = 3 Thus the first term is −17 and the common difference is 3.
