WebFeb 20, 2024 · To find the N th term in the Geometric Progression series we use the simple … WebMar 29, 2024 · Transcript. Example 4, In an A.P. if mth term is n and the nth term is m, where m n, find the pth term. We know that an = a + (n 1) d i.e. nth term = a + (n 1) d Thus, mth term = am = a + (m 1) d It is given that mth term is n a + (m 1) d = n Also, it is given that nth term is m a + (n 1) d = m First we find common difference, Subtracting (2) from (1) [a + (m 1) d] …

WebNov 1, 2024 · Expanding and cancelling terms we get $\frac{2an}{d} + n^2 = \frac{a(m+r)}{d} + mr$. Transposing terms, we have $\frac{a}{d}(2n-m-r) = mr-n^2$. Consequently, $\frac ad = \frac{mr - n^2}{2n-m-r}$. Since we know the answer is $\frac{-n}{2}$, let us rewrite the above as $\frac{-n}{2} \times \frac{2mr - 2n^2}{n(m+r) - 2n^2}$, where we multiplied ... WebExample 1: If the first term of an AP is 67 and the common difference is -13, find the sum of the first 20 terms. Solution: Here, a = 67 and d= -13 S n = n/2 [2a+ (n-1)d] S 20 =20/2 [2×67+ (20-1) (-13)] S 20 = 10 [134 – 247] S 20 = -1130 So, the sum of the first 20 terms is -1130. smart cars for sale kelowna
