WebMar 6, 2024 · To find 20th term form the last term we consider the sequence as follows a = 253 and d = 3 - 8 = -5 an = a + (n - 1)d a20 = a + (20 - 1)d = 253 + 19 × (-5) = 253 - 95 = … WebFirst, we will find the number of terms in the sequence. t n=a+(n−1)d 253=3+(n−1)(5) 253=5n−2orn=51. So, there are a total of 51 terms in the sequence. The 20th term from the last is same as the 32nd term from the first. Hence, t 32=3+(32−1)(5) t 32=3+31(5) t 32=158..
