Heya !!
Common difference ( D ) = 2
And,
A22 = 149
A + 21D = 149
A + 21 × 2 = 149
A + 42 = 149
A = 149 - 42
A = 107
First term ( A ) = 107
Therefore,
S22 = 22/2 × [ 2 × 107 + ( 22 - 1 ) × 2 ]
=> 11 × ( 214 + 42 )
=> 11 × 256
=> 2816 [ Answer ]

Hello dude !
♠ Here is your answer ♠
____________________________________________________________________________________
d = 2
A22 = 149
A + 21D = 149
A + 21 × 2 = 149
A = 149 - 42
A = 107
First term= 107
S22 = 22/2 × [2 × 107+( 22- 1 ) × 2]
=11 × ( 214 + 42 )
=2816.
