Series are sum of prime number
11+7 = 18, 18 +11 = 29, 29+13 = 42, 42 +17 = 59, 59+19 = 78,
So, 78 in place of 80
(2+7) ×1 = 9
(9+6) ×2 = 30
(30+5) ×3 = 105
So, 30 in place of 32
×11, ×9, ×7, ×5, ×3, ×1, ….
17325×3 = 51975 in place of 34650
Series is ‘(×3)’
So, wrong no is 10.
+4, +12, +20, +28, +36, +44, ……
So, 46 is wrong no. it should be 44.
