321. 13, 16, 23, 36, 57, 88, ?, 188

Check answer and explanation

Answer: 131

Explanation 88 + 43 = 131 13+3=16 by skipping next 1 odd digit that is 5 we will add 7 to 16 16+7=23 by skipping next 2 odd digit to seven we will add 13 to 23 23+13=36 by skipping next 3 odd digit to 13 (i.e 15,17,19) we will ad 21 to 36 36+21=57 by skipping next 4 odd digit to 21 (i.e 23,25,27,29) we will ad 31 to 57 57+31=88 by skipping next 5 odd digit to 31 (i.e 33,35,37,39,41) we will ad 43 to 88 88+43=131`

322. The sum of the first 12 numbers of the series: 2, 6, 10, 14, ______?

Check answer and explanation

Answer: 288

Explanation This is an arithmetic series: 2, 6, 10, 14, ... First term (a) = 2 Common difference (d) = 6 - 2 = 4 Number of terms (n) = 12 Sum of n terms of an arithmetic series: S = n/2 × [2a + (n - 1)d] S = 12/2 × [2×2 + (12 - 1)×4] S = 6 × [4 + 44] = 6 × 48 = 288

323. What are the missing numbers in 3, 8, 13, 18, 23, _____, _____?

Check answer and explanation

Answer: 28, 33

327. Complete the series: 1, 1, 8, 4, 27, 9 _____?

Check answer and explanation

Answer: 64

Explanation The pattern alternates between cubes and squares: - 1³ = 1 - 1² = 1 - 2³ = 8 - 2² = 4 - 3³ = 27 - 3² = 9 - 4³ = 64 So, the next term is 64 . Last verified on 30-03-2026

328. Find the number of terms in the sequence 4, 8, 16, 32, _____ 512.

Check answer and explanation

Answer: 8

Explanation GP series = 4, 8, 16, 32, ... 512. FORMULA USED: Tn = ar(n-1) SOLUTION: GP series = 4, 8, 16, 32, ... 512. Tn = ar(n-1) ⇒ 512 = 4 × 2(n - 1) ⇒ 128 = 2(n - 1) ⇒ 27 = 2(n - 1) Now comparing powers we obtain; ⇒ n - 1 = 7 ⇒ n = 8
